Ray white realestate breach

Ok so I’m wondering what I should/could do or what you would do in this situation,

My current landlord has just recently changed realestate agents and are planning on selling the entire apartment complex, which means the obvious and occasional viewings , which I don’t mind given the legal 24 hours notice to enter the property , even with barely the 24hours notice I’m ok with it… that’s not a problem for me, but it’s happened everyday this week so far last Friday 2 viewings , Monday 2 more and then again on Tuesday , yesterday had a painter come in to do “repairs” so pretty much no privacy and yet this still isn’t my main issue, I then get given a email by the realestate threatening a breach notice because I’m late on my weekly rent by less then a day. Fine fair enough… technically within the rights of a breach… BUT THEN TODAY!!! As I was still in bed,a realestate agent from ray white literally unlocks my door and walks in, I’m standing there in my PJS not knowing wtf is going on , he’s shocked to see that I’m home and tells me hey the painters here and needs to do more work on the house, please note: no notice was given, no knock on my door, he literally unlocks my apartment and strolls in….. is this not a breach? And look I’m not mad at the painters he’s just trying to do his job, but surely this is a breach in many ways..?! . Also been told there’s 2 more showings tomorrow so that’s 5 days in a row (every day this week) But fuck me dead Ray white…. What can I or should I do???

Please note: I live in QLD AUSTRALIA
