Beginnings and Pressures

We formed our own business to capture opportunities in Australia being let go to USA and UK too much! We are an Australian-based, agile, niche, hi-tech, international, competitive microbusiness started in 1997 with a rich diversity of experience to draw on. We are basic contractors on small, specific jobs - no open-ended work. We have tertiary qualifications (BSc, Grad Dip IM-Lib) to draw on.

We are an incorporated service-based company in the knowledge economy. Dwight Walker is our creator, director and manager. We have our own online resources and use the Internet heavily. We travel to other cities outside of where we are based to setup jobs for customers or work onsite.

We started in 1997 because we could see opportunities for working on the Internet and most Australian companies were sitting back waiting for USA to do it first then copy them. In 2010, most other companies have caught up and overtaken us. We decided to get in first and not lose the opportunity. This took risk on our part but we were not willing to see Australia left in the dust yet again but be the leading force in the World Wide Web industry, so we went for it.

We have hit a few disasters in the IT industry. We barely survived the dot com crash in 2001 due to being agile and willing to change and grow with the world economical conditions, going mobile from 2003 after moving to Orange from Sydney which saved on rental and storage costs.

After the Global Financial Crisis in 2008, we eventually moved to Brisbane in 2013 due to a series of failures.

Most of our customers used to contact us via phone, fax or email but now our local presence is more important. Before it was just our internet and mobile phone connectivity.

Most of our early customers were in USA, Canada and UK, not Australia (as usually is the case with our remote country), so we got very good at dealing with remote customers and still have our customers nearby and away from where we are based, using the Internet and onsite as our main vehicles for business.

From 2000, we moved into open source software such as Linux and away from Microsoft to cut costs and remain competitive. It was a risk but we have built up a niche now which has been steadily overtaken by hundreds of Indian Web developers at a much lower price point than us.

In 2013, we partnered with Amazon Web Services and Microsoft for cloud services.

In October 2016, we were now interested in digital publications indexing. We are mainly a Web developer and do backend development, EPUB publishing and taught violin and piano. Arts were replacing science as main source of income e.g. editing, publishing, violin teaching to upgrade IT infrastructure to grow business.

Since March 2020, due to COVID-19, music lessons stopped and IT consulting and Web development regrew again. Publishing has taken a very long time to complete.

Business Structure

In August 2017, due to insurance, we split the company into 3 divisions:

  • Division 1: IT (WWWalker Web Development Pty Ltd)
  • Division 2: Music Teaching (WWWalker Web Development Pty Ltd)
  • Sole Trader Music Performance (HD Walker)

In June 2020, we changed HD Walker to recycling supply chain management and music teaching ceased due to COVID-19.


In 2014-2020, we studied robotics and supply chain management via QUT and MIT MOOCs and got excellent marks. We went into embedded systems, systems programming, cloud computing, WordPress, remote support, Javascript, TypeScript interactivity and ecommerce.

In November 2017 to November 2019 and in 2022, to broaden our enterprise skills as hosting and domain white label service and increase social media marketing and data mining skills, we studied at CSU IT Masters MOOC and got high marks especially in security and data mining subjects:

  • Project Management Updated - PMBOK7
  • PRINCE2 Primer,
  • Cyber warfare and Terrorism,
  • Enterprise Cyber Security and
  • Phishing Countermeasures
  • Computer Network Fundamentals
  • Applied Social Media Marketing
  • Introduction to Knowledge Discovery and Data Mining


As of 19 April 2019, we switched from Oracle JDK to OpenJDK due to Oracle licensing commercial use of Java. This may have to be revised as some software will only run on Oracle Java.
