Seriously, I would be looking to move out – which may also require taking action at Fair Trading to allow you to break your lease.
It sounds like you are in one of only two units – and that makes things tricky when it comes to sharing electricity etc. It may well be that the landlord isn’t even aware of what the agent is saying and doing.
I strongly recommend you have a look at the Tenants Union website (www.tenants.org.au) where there is a wealth of information about your rights (including, I think, information about electricity supplies).
But let’s face it, as soon as your lease is up, the landlords are probably going to want you out anyway. So start looking for alternatives now.
And by the way, some councils won’t allow street parking permits for strata residents, regardless of whether they have parking in their block or not. But again, you may just be at the mercy of a lazy rental agent.
