Murphy has formed a strategic partnership with Australia-based Abergeldie Complex Infrastructure, taking a 40% stake in the business.
Headquartered in Sydney, Abergeldie Complex Infrastructure was established in 1994 by Mick Boyle and his wife Robin Craig and has since expanded its operational presence across Australia and New Zealand.
The business today has more than 800 employees and turned over AUD $676m (£330m) last year. Like Murphy, it remains family-owned and operates across the utilities, road, rail and energy sectors. With Murphy by its side, Abergeldie is now planning to take on larger infrastructure projects.
For Murphy, the investment in Abergeldie represents a further internationalisation of the business. Having originally focused on the UK and Ireland since its foundation in 1951, Murphy established a presence in Canada in 2014 through a joint venture with Surerus Pipeline Inc and expanded into the USA with the acquisition of WHC Energy Services in 2023.

Murphy chief executive John Murphy said: “Having expanded into North America in recent years, this investment marks the latest step in our plans to extend our geographical reach whilst remaining focused on our commitment to improving life by delivering world-class infrastructure.
“I am delighted that we have been able to find a partner who shares so many of the same values as us.
“We are very positive on the outlook for the Australian market and I am looking forward to working with the Abergeldie team to help them deliver on the next exciting stage of their growth plans, building on the great work they have done over the past 30 years.”
