Maps of East Malaysia
Just back from Europe so missed your first post.
If you are still in Australia go along to Air Support or any of the other pilot shops at the GA airfields, you should be able to get the ONC 1:1m and 1:500 maps. The one you require (1m) is ONC L-11. The 1:500 have a suffix A, B, C and D for the quadrants.
Hope that helps
