Buying in Qld

Looking at buying something in SE Qld in the 1M range. We have about $240k we can use towards a deposit. My income is 150k before bonuses (last year I did significantly more post bonus), hers is 95k. One thing to note she is pregnant so will be on maternity for a year following the purchase (she’ll go back to current employer on 95k after). Is it possible? Can we go with mainstream lenders?
