Think Smaller Even for the Bigger Projects

We’re not the biggest earthmoving company. And we’re glad we’re not.


We’re not the company that sends a different guy every time. Got his tickets 6 months ago. Then when he gets onsite. Its old machinery. He’s whinging that the machine he’s got is busted. And he’s been asking his boss to fix it for the last 3 months.

That’s not RONMAC.

You need a plant company that puts you first. Knows you’re on a deadline and needs a company that can get the job done right the first time. We pay attention to the detail. Both on and off-site. Saving you time, money and hassles. Being a family-owned company allows us to have a finger on the pulse day in, day out. And we won’t take it off until your job is complete.

Time Is Money

No one likes breakdowns. But it’s not enough to hope that machines won’t go unserviceable. Breakdowns disrupt deadlines, costing you time and money.

At RONMAC we’ve got a very NEW FLEET of machines. Because we are a family-owned business, we pay attention to detail and only buy the highest quality equipment.

That’s why our customers enjoy increased reliability, reduced risk of breakdowns and the fulfilment of project schedules.

Focus On What Matters

Every job is different with its own specific set of problems and challenges. You’re a problem solver and you need a plant company that works with you, not against you.

What sets us apart is personal service. We give you a tailored solution for your needs. We believe that a rigid one size fits all solution that other companies offer never yields the results our clients need.

Dan Fulton, Owner at ALLROADS

We’ve been using RONMAC for about 7 years. Great service.

For me, when I’m chasing a machine I won’t get off the phone until its sorted. I can call Brent whenever and he will make it happen.

All their gear is new, which is good.

I can just send them to a job and they’ll get it done. I know it’ll be done properly and I don’t have to worry about it.

I Highly recommend them.

Jon Fulton, Owner at ALLROADS

Great service. Keep it up.

Dale Henry, Shadforth Foreman

Really impressed with the RONMAC team. they’re great. I highly recommend them.

I had one of our machines break down. I really needed to get a footing dug because I had concrete coming in a couple of days. Everyone’s been flat out lately and I rung Brent expecting him not to have any machines available. He shuffled machines around for me so he could get me one to finish this footing. I was so grateful. 


Mike Stuck, Halls Foreman

We’ve been using RONMAC for about 16 months now on various projects.

We’re really happy with their service. Since day one they’ve always rocked up on time. Their guys are good blokes and get along with my crew. Which is important to me.  From what I’ve seen they’re all great operators.

Really happy with the service we’ll continue to use them. 

Running in the family for 4 generations

RONMAC founders, Craig and Rhonda McGeechan started C.R & R.M McGeechan plumbing and drainage in 1986. Craig is a 3rd generation plumber and had been helping his dad with plumbing since he was a kid. He knew there was a need for quality plumbing and draining services to the South of Brisbane.

In 2001 the business was doing more drainage than anything else. To do this it had to subcontract earthmoving machinery and operators. The problem, most of the time machine operators would turn up late or not at all. This was holding back the business. Craig saw there was a real need for earthmovers that understood what plumbers wanted.

So, at the end of 2001, a small green 1.1-ton excavator was acquired, which was the start of RONMAC, the new direction for the business that is servicing all our clients with excellence up until today
