He's worked across most parts of the WA plumbing industry. After his five-year apprenticeship at Practical Plumbing & Gas, he moved through Browns Plumbing (real-estate maintenance), Altona Plumbing & Civil (commercial maintenance, schools, and the Australian Marine Complex), Robinson Buildtech (government schools, Perth Airport, city councils), and Boeing Plumbing, where he was a maintenance plumber for ABN Group, the parent of Dale Alcock Homes, Celebration Homes and APG.1 He went on to become Operations Manager at Property Plumbing & Gas before earning his contractor's licence and starting Unrivalled in 2023.1

What types of properties does Joshua usually work on?
A mix. His career history sits across new-home plumbing for major builders (Dale Alcock, Celebration Homes, APG via ABN Group), commercial maintenance (schools, Perth Airport, city councils, the Australian Marine Complex), and rental/strata maintenance for real-estate portfolios.1 That breadth means he's comfortable on a one-off blocked drain at a private home and equally on a 100-unit strata maintenance program.
Why use a chapter plumber instead of finding one on Google?
Accountability. BNI chapters hold one seat per trade, so Joshua's reputation is staked weekly in front of 19 other business owners. In the 2024-25 reporting year BNI Coastal recorded $2,287,103 in closed business between members at the BNI WA Awards, referrals only continue at that scale when members consistently deliver.
