Episode summary
Why AustralianSuper's CIO draws inspiration from Warren Buffet?
Summary
Mark Delaney says AustralianSuper is still built around long-term investing, with his role focused on preparing the team to run the portfolio well through succession. He traces his career through three formative stages: demanding early work in government economics, learning the craft through CFA study and global fixed income, and then moving into superannuation to manage a diversified portfolio across asset classes.
He argues that investors should stay disciplined in private markets. Delaney says private equity, infrastructure and real estate have largely gone through a valuation reset after higher rates, while private credit is drawing the most attention in 2026 because of AI-related financing demand. He does not think private credit is in a bubble, but says the key test is whether borrowers have the cash flow and balance sheet strength to repay.
On public markets and geopolitics, Delaney says the world is riskier than it was two years ago, but that does not automatically mean a wholesale portfolio shift. AustralianSuper has stayed fully exposed to US equities because of the AI boom, while also diversifying more at the manager level. He repeatedly returns to Warren Buffett’s influence: study great investors, avoid bad businesses, and ask whether you trust the manager, understand the opportunity, and think it is the right time to buy.
Key takeaways
- Delaney says private credit is tight on spreads in 2026, but he does not view it as a bubble because borrower quality and repayment capacity matter most.
- He says private equity and real estate have largely normalized after higher rates and earlier valuation pressure.
- AustralianSuper has kept a fairly full weight in US equities because Delaney remains a believer in the AI boom.
- Delaney says the best private-credit managers are the ones who avoid losers through diversification, robust frameworks, and a strong track record.
- He says Warren Buffett’s influence shows up in his investment filters: trust the manager, understand the investment, and judge timing carefully.

How the episode opens
If you found a bag with $10 billion today, what would you do? — What I would do, I would invest it if I had the opportunity.
Exactly the same way as I've got the Australian super balance plan invested cuz that portfolio reflects my best ideas and the team's best ideas of the people I trust. I think in the months I got left, the key thing is to ensure that the people who are doing the day-to-day running the portfolio are really well equipped, have the best skills, and are confident in executing on their judgment. So my job is to work with my people and they're a great team to basically do for them to do their best in the portfolio and not to be worried about any changes because their judgment is a good judgment and they'll do a good job.
The thing about surfing is that you don't think about anything else but surfing. You're sitting out there, you're paddling out there and then you're sitting on the board, look at the waves coming and say, "Is it this one? Is it that one?
or whatever. There's no time for anything else. It's completely mind clearing.
And then when you come out and the water's washed over your head and over your face, you sit back fresh and you sit on the beach and you just go, "Oh, that's a job done. That's just fantastic. And that clarity of the mind, clearing of the mind, you know, a lot of philosophies about that and whatever then sets you up to then take on the more complex or difficult decisions.
Welcome back to another episode of the allocators playbook. Today I have someone very special with me who apart from being an exceptional investor loves the water like I do.
