It's causing massive problems (mostly around retirement homes) because the network is operating at around 270v in the middle of the day, in a suburb with lots of solar (should be about 240v).
No it does not cause problems. In Australia, solar inverters shut off when the grid voltage reaches 250 Volts, it is what they are designed to do. The utilities sometimes jack up the grid voltage to shut down the solar inverters, that way they don't have to pay for the electricity they produce.
