A low loader 48 hours . By sea, how far is it and how fast is the boat?

2000 miles give or take @ 5 knots average is 400 hours sea time

I think you'll need a minimum of 3 or 4 weeks just to get up the NSW coast, wrong time of year really to be going long distance North. But its possible to poke out before a southerly buster/southerly change and just hold on!!!
Usual practice is to wait for the front to pass & ride up on its back.
I would be very, very impressed if you was lucky enough to get the weather to do the entire journey in a month.
Another option would be to travel/motor north at night, when generally the NE'ers ease off.

I did Darwin to Perth a few months ago in 18 days with 3 rest days. sail around the clock when weather permits and you should manage it in a month.
Adams 10 is no slouch so if you have the crew work on 130 mile days.
