Try Aerotropics up at Horn Island.....great company and plenty of twin hours when I was there from 2001 to 2002. You will probably need to do about 6 weeks in the hangar at CNS before going up to Horn....logged about 1500 hrs in just under 2 yrs.....they have a fleet of multi-engines....no singles....I hear they are finding it hard to find experienced drivers...if you have around 1000 hrs TT....I recommend jumping in your car and driving up there....I drove up there in Jan and got a position in the hangar within 3 weeks and then 6 weeks later up to Horn and started on the PN68 and BN2P then moved onto AC500, BE58 and PA31
GOOD LUCK MATE !!!
