Hi, I am an accountant :-) The claiming of childcare relates to the non-deductible portion of self education (basically the ATO deduct $250 from your expenses so you can put in expenses which would normally be non deductible ie childcare. This means your deduction for self education wont be reduced by the $250. Not sure if this makes sense. Tolls would be a deductible expense and travel to and from uni is also deductible, as is parking! Tolls are separate to the cents per kilometres claim :-) So you win on all counts! Let me know if you need any more help!
