✨ 15 Years! ✨

This year we celebrate 15 years of Shane “Watto” Watson and O’Connors. During this time, Watto has been an invaluable leader within our construction team where he has delivered on several pinnacle projects for the State of South Australia, including but not limited to by any means RAAF Base, HNA HC1, Learning Hub, Illuminate, Adelaide Convention Centre, AIR555 and SIM, NEXTDC, Health Innovation Building, Osborne South Redevelopment Project, and Osborne North Redevelopment Project.

Watto brings to the team a high level of technical skill and understanding as well as, a long history of delivering our scope with superior quality control, high site safety standards and efficient site operations.

Watto is a kind and considerate team player who offers leadership and assistance to his mates on site when needed. Away from work, he is a devoted family man who is adored by his wife Kelly and children, Tayla and Blake. Shane has a quiet obsession with the Adelaide Crows, enjoys camping, fishing, and spending time with his family.

Congratulations Watto!

Thank you for your hard work, dedication, and commitment. We look forward to many more years ahead.

Cleaning up those Pommie batsmen

This season Greg Lea is sponsored by O’Connor Services, and with them backing him, Greg’s season is set to deliver quality workmanship from start to finish.

Greg might be from Oz, but he’s no stranger to bringing the thunder Down Under-style – a true-blue performer who’s always ready to get stuck in and do the hard yakka. Whether he’s steadying the innings or tightening things up with the ball, Greg’s the kind of player who gets the job done with no fuss and no shortcuts.

And with O’Connor Services – the go-to name in Air conditioning – as his sponsor, it’s no wonder Greg’s got all the right tools at his disposal. They know a thing or two about pressure, and they’re backing a bloke who can be relied upon to keep his cool in the summer sun, or turn up the heat on unsuspecting batsmen on a cold rainy afternoon.

Here’s to a season of clean outs, cracking form, and keeping the fans happy – proudly powered by a partnership that’s built on trust, quality, and a bit of Aussie elbow grease.

It is with profound sadness and a heavy heart that we announce the loss of Creagh O’Connor, who passed away on Wednesday, 26 February at the age of 88 after a full and resilient life.

Creagh was a Director of O’Connors from 1999 to 2016 during which time he was an inspiration to us all and reminded us to always see the good in people—a true gentleman and a pillar of T. O’Connor & Sons and O'Connors.

You will be deeply missed, Creagh but your legacy will live on through O’Connors, and the industries you helped build.

Descansa en paz, Poppa.

Hoo Roo Dunc!!

It has been 10 years since the passing of one of our foundation pillars, Duncan Robertson. While this type of post may not be common, we felt it was important to remember a man who meant, and continues to mean, so much to our One O’Connors team.

Thinking of you Dunc!🍻

Time to celebrate, with a Coopers!

Our experienced team has effectively and efficiently completed end-to-end works for the mechanical services at the new world-class visitor centre, microbrewery and whisky distillery at its Regency Park site.

This project has not only been unique and enjoyable but we are excited to be apart of something with such wow factor! We do not doubt that the unique curved design of the new two-storey development, inspired by the iconic Coopers’ label rondel, will have visitors impressed from the moment they arrive!

Our team has worked collaboratively and systematically to deliver a project of quality and excellence, and we are extremely pleased to have done so alongside fellow South Australian and family owned businesses.

It is not everyday that someone receives the highest honour in the HVAC&R and building services industry…being inducted into the Hall of Fame!! During the largest HVAC&R and building services exhibition in Australia!

So, it is extremely exciting for us to announce that our Managing Director, Andrew O'Connor has been inducted into the ARBS Exhibitions Ltd Hall of Fame, a recognition of his substantial contributions to the HVAC&R landscape.

Andrew’s family have a long and rich heritage in the HVAC&R industry - spanning five generations and 130 years since his great grandfather Thomas started a plumbing, heating and ventilation business. His leadership roles, as state and national president of AMCA Australia, and Specialist Contractors Association highlight his advocacy for skill enhancement and equitable and logical risk allocation. Andrew's vision materialised with O'Connors, an institution synonymous with innovation in South Australia's mechanical services sector, emphasising the cultivation of local talent and apprenticeships.

His endeavours focus on developing and mentoring great people within a good work environment. This is evident in the development of future industry stewards, ensuring a thriving sector for generations to come.

Andrew's generous spirit and strategic leadership have not only fostered a team of adept professionals but also promoted a culture of respect and collaboration. His business acumen and passion for the industry resonate through his company's growth and his commitment to the betterment of the field.

These achievements and his profound influence on the industry culminate in his induction into the ARBS Exhibitions Ltd 2024 .

Congratulations Andrew, this is a tremendous lifetime achievement, and very much well deserved! O’Connors and its people appreciate your ongoing and unwavering commitment to the development of good people.

We thank the AMCA Australia for this recognition.

The Tri-Gen Plant Upgrade, which our Service Projects team is undertaking, in conjunction with Sarah Constructions and WSP in Australia, is progressing smoothly at University of Adelaide’s Plant Accelerator building!

To date, we have demolished the existing AHU’s that supplied the Northern Smart Houses, and the new upgraded AHU’s are now installed and functioning. In addition, the existing Tri-Gen equipment (micro-turbines and the absorption chiller) has been removed, allowing installation of the new chillers, pumps and other associated equipment by the One O’Connors team.

Modification of the existing heating hot water and condenser water is currently ongoing, in order to facilitate the new boilers and cooling tower. Furthermore, these project works are being undertaken whilst allowing the facility (Australian Plant Phenomics Facility) to continue their important research within the building.
