WordPress Developer Sydney — Custom WordPress Development for Australian Businesses
Custom code. Custom plugins. No templates. Built by a Sydney team that has lived and breathed WordPress since its early days.
WordPress is What We Do — And We Do It Better Than Most
WordPress was launched in 2003. Uniweb started building on it in 2011, when most agencies were still treating it as a blogging platform. Over fifteen years we have watched WordPress evolve from a simple content management system into the most powerful website platform on the internet — and we have evolved with it every step of the way.
Today WordPress powers over 43% of all websites globally. But knowing how to install WordPress and knowing how to truly build on it are two very different things. Templates, page builders, and drag-and-drop tools can produce a website — but they cannot produce a fast, secure, scalable, and truly custom WordPress solution. That requires developers who understand the core architecture, who write clean PHP, who know when to use a plugin and when to build one from scratch.
That is what our Sydney-based WordPress development team does every day.
LETS DISCUSS YOUR WORDPRESS REQUIREMENT
What we build on WordPress
From simple WordPress websites to complex custom plugin builds, our Sydney development team handles every aspect of WordPress development in-house.
Custom WordPress Theme Development
We do not use pre-built themes. Every WordPress website we build starts with a custom theme coded specifically for your business. That means no bloated CSS, no unused features slowing your site down, no generic layouts shared with thousands of other websites. Your theme is written from scratch to your brief, your brand, and your performance requirements.
Custom Plugin Development
This is where most agencies hit a wall — and where we do our best work. If you need a feature that does not exist as an off-the-shelf plugin, we build it. Our developers have built custom plugins for booking systems, membership portals, wholesale pricing engines, B2B account management, custom product configurators, advanced search and filtering, automated email workflows, API integrations, and more. If you can describe what you need, we can build it in WordPress.
WooCommerce Development
WooCommerce is the world’s leading ecommerce platform and we are deeply experienced with it. From straightforward online stores to complex B2B wholesale systems with custom pricing tiers, approval workflows, and on-account payment options — we build WooCommerce solutions that go well beyond what out-of-the-box setups can achieve. We have built WooCommerce stores for retailers, wholesalers, subscription businesses, service providers, and everything in between.
WordPress Plugin Customisation
Sometimes an existing plugin gets you 80% of the way there but not quite where you need to be. Rather than working around its limitations, we go into the code and customise it to fit your exact requirements. We have modified and extended dozens of popular WordPress plugins for clients across Australia.
WordPress Performance Optimisation
A slow WordPress website loses visitors and rankings. We optimise WordPress installations for Core Web Vitals, implement caching solutions, clean up database bloat, eliminate render-blocking resources, and configure server-level performance improvements. We have taken sites from failing Core Web Vitals scores to passing across mobile and desktop.
WordPress Security and Hardening
WordPress is the most targeted platform on the internet precisely because it is the most popular. We harden WordPress installations against common attack vectors, implement file permission lockdowns, set up WAF rules, monitor for malware, and have experience cleaning up and rebuilding sites that have been compromised. Security is built into every site we deliver.
WordPress Migrations
Moving from another platform to WordPress, from one host to another, or from a legacy WordPress setup to a clean modern build — we handle migrations without downtime, data loss, or SEO disruption.
WordPress Migrations
We connect WordPress to virtually any external system via API. CRMs like Salesforce and HubSpot, accounting software like Xero and MYOB, email platforms like Mailchimp and Klaviyo, payment gateways, booking systems, and custom business tools. If the third party system has an API, we can integrate it cleanly into your WordPress website or WooCommerce store.
WordPress Support and Troubleshooting
If your WordPress website is broken, slow, throwing errors, or has been hacked, we can diagnose and fix it fast. We regularly take on WordPress sites that have been poorly built or abandoned by other developers and bring them back to a working standard. For ongoing peace of mind, our hosting and maintenance package covers all updates, security monitoring, and unlimited support from $330 per year.

WordPress Development for Agencies and Technical Partners
We work with businesses directly — but we also partner with design agencies, marketing firms, IT companies, and SEO consultants who need a reliable WordPress development team behind them.
If you are a design agency that produces stunning mockups but needs a development partner to bring them to life in WordPress, we can do that. If you are an SEO agency that needs technical WordPress work done for your clients without you having to manage it yourself, we can do that too. If you are an IT company whose client needs a custom WordPress plugin or integration built, we are the team to call.
We work quietly in the background, deliver to your brief, and respect your client relationships. White label arrangements are available for agencies that need it.

We Have Worked With WordPress Since Its Early Iterations
When we started building on WordPress in 2011, there was no Gutenberg editor, no block-based themes, no full site editing. There was core WordPress, PHP, MySQL, and the need to write everything yourself. That foundation is what separates our team from developers who learned WordPress through page builders.
We have built on every major version of WordPress. We understand the template hierarchy, the hook system, the plugin API, the REST API, and how WordPress interacts with the server at every level. When something breaks, and with WordPress, something always eventually breaks, we know exactly where to look and how to fix it fast.
Over 1,000 WordPress websites delivered. 50+ custom plugins built and deployed. Clients ranging from sole traders and local service businesses in Western Sydney to established SMEs, professional services firms, and growing ecommerce businesses across all states of Australia.

What is the difference between a WordPress developer and a web designer?
Web designer focuses on how a website looks — layout, colours, typography, and user experience. A WordPress developer focuses on how it works — writing the code, building the functionality, and making sure the technical foundations are solid. At Uniweb we do both, which means your website looks great and works exactly the way it should.
Can you build custom features that don't exist as WordPress plugins?
Yes. Custom feature development is one of our core specialities. Our developers write custom WordPress plugins from scratch to deliver functionality that does not exist off the shelf. Booking systems, membership portals, wholesale pricing engines, API integrations, custom calculators — if you can describe what you need, we can build it.
Do you work with existing WordPress websites or only build new ones?
Both. We take on new WordPress builds from scratch, redesigns of existing WordPress sites, performance optimisation of slow or poorly built sites, security hardening of vulnerable sites, and ongoing maintenance and support. We also regularly inherit WordPress websites from other developers and bring them up to a proper standard.
Can you integrate WordPress with third party systems?
Yes. We have experience integrating WordPress and WooCommerce with CRMs, accounting software, email marketing platforms, payment gateways, booking systems, ERP systems, and custom APIs. If the third party system has an API, we can connect it to WordPress.
Do you do white label WordPress development for agencies?
Yes. We work with design agencies, marketing firms, SEO consultants, and IT companies as a white label development partner. We build to your brief, respect your client relationships, and work quietly in the background. Talk to us about how we can support your agency’s WordPress projects.
How much does custom WordPress development cost?
Cost depends entirely on the scope of the project. A standard custom WordPress website starts from $1,320. Custom plugin development, theme development, and complex WooCommerce builds are quoted individually based on your requirements. For a detailed quote based on your specific needs, contact us or view our web design packages for standard pricing.
Are you based in Sydney?
Yes. Our development team is based in Harris Park, Parramatta in Western Sydney. We work with businesses across Sydney, Brisbane, Melbourne, Perth, and throughout Australia — all managed by our in-house team with a dedicated account manager for every project.
