Every conversation about Queensland’s labour shortage lands in the same place. Hire more people. Train more apprentices. Bring in more migrants. It sounds sensible enough and it’s the plan most construction businesses reach for first. Yet somehow the industry keeps hiring while output keeps slipping the other way, quarter after quarter. So what if the real problem was never how many people are on site, but rather a system that’s leaking faster than anyone can fill it?
More Hands Won’t Fix a Leaking Bucket
Ask most construction business owners how to lift productivity and you’ll get the same answer. Bring in more people. It feels obvious. More hands on site should mean more output. Yet across Queensland, headcount keeps climbing while the numbers that matter keep moving the other way.
That’s not a hunch. The Productivity Commission found it now takes roughly twice as many labour hours to build the same home as it did back in 1995.¹ Equipment and training have both improved since then. Somehow, each hour on the tools produces about half of what it used to.
Picture a bucket with a hole in the bottom. Pouring in more water doesn’t fill it. It just means working harder to hold the same level, or falling behind despite the extra effort. Construction has been pouring in more workers for years. The level hasn’t moved.
The Leak Nobody’s Looking At
So where does all that extra effort actually go? Not into idle sites or empty rosters, but into a system that quietly wastes the people already on the tools. Rigid rostering across Queensland often keeps expensive trades well short of a full working week.
Dexus CEO Ross Du Vernet put it plainly last year. On big Queensland sites, it’s not unusual to get 2.5 productive days a week once rostered days off are factored in, effectively a 9-day fortnight.² Businesses end up paying premium trade wages for part time output.
It’s the construction equivalent of paying a doctor’s rate for two days of surgery in a five day week. The skill hasn’t gone anywhere. Neither has the cost. What’s missing is a system built to use both properly, not more hiring.
A Slow Leak Still Empties the Bucket
This isn’t a one-off wrinkle that irons itself out over time. It’s been compounding for three decades. The businesses feeling the squeeze today are inheriting a gap that’s been widening quietly since well before most of their current workforce started.
The same Productivity Commission analysis found construction labour productivity has fallen 12% since 1995, while the broader economy grew 49% over the same period.¹ Two industries, same starting line, wildly different outcomes. One kept fixing its own leaks. The other kept adding water.
That gap is why hiring alone can’t be the answer. Every extra worker added to a leaking system adds cost at the same rate the leak was already draining it. The maths doesn’t improve. It just gets bigger, taking the bill sitting underneath it along with it.
Plugging the Leak, Not Filling the Bucket
If you’re running a construction business right now, you already know this leak by feel, even without a name for it. It’s the tradie waiting on a delivery. The roster that doesn’t match the week’s actual workload. Paying for more than you’re getting.
Fixing it isn’t about finding more people. It’s about the right person on the right task at the right time, without a full time hire you only need for two days, or a slice of margin lost to labour hire. That’s what Casu’s direct casual employment is built for.
The leak was never going to close itself. No amount of extra hiring was ever going to close it either. What closes it is fixing where the water is actually escaping, so every hand you bring on finally adds up to something. That’s not a hiring problem. That’s a leak.
