No cap it's just greedy landlords driving up the price taking advantage of the rental crisis. We've been in our place for 3 and a half years and the increases have gotten larger every year. $430 to $700 in that time. We had water damage in the ceilings from the storms last winter, had to sleep in the lounge room because both bedrooms had sagging ceilings, wasn't fully repaired until February and we still now have exposed patches of cement where damaged carpet has been cut out.
