subdividing our investment property

Hi
could anyone suggest a good accountant or financial adviser for us? We are south of Brisbane City. We have an investment property which we are going to subdivide and sell to decrease the morgage on our primary place of residence but are unsure which would be the best way. We are also thinking of selling our current primary place of residence and moving back into the ip short term to finance this. My main goal is to have a small morgage on our primary place and have an investment property set up correctly.AT the moment we owe roughly the same amount on both our properties.
Would appreciate any advice.
