Regarding Australian trailers - I would run away screaming. Not to put too fine a point on it, but I recently had a horrible experience with them.
I ordered an aluminium trailer from them and was told two week delivery. Two months later, after weekly threats and shouting matches and lots of frustration, my trailer arrived. The dimensions were completely wrong and when I inspected the final product, I was appalled at the quality. (Rough edges, sharp edges, untightened bolts, etc.)
Fortunately, I got my deposit back, but I wanted two months - for SFA.
As I said - I would run away screaming...
