"Me and Lou struggled with jet lag for a while but we are peaking now and have adjusted well to the heat. The heat makes training a lot harder but it is good for making fight weight. We have been sweating out 1kg-2kg each training."
The Wanganui Assassins Guild fighters will need all their skills and street savvy during the strict knockout competition, featuring some of the best in the world in their respective weight divisions.
The lanky 2.032-metre (6ft 8in) Gallacher will compete in the cruiser under-86kg A class weight division in Malaysia. In contrast, Fuller is tiny, barely scratching the 1.5m mark (5ft 2in) and will fight in the under-45kg women's grade.
Just before the pair left Wanganui for Malaysia, Gallacher was weighing in 89kg and Fuller just 1kg above her fighting weight at 46kg.
