Do not trust this person! They pretend that they have tickets to sell. Will ask to do payment through Cardless cash.

Thanks I received a text message from Gumtree offering concert tickets as well. Asked to deposit money through Commbank branch. Cheers to the warning.

I also received a message offering concert tickets after I posted that I was looking for them on Gumtree - thanks to the poster above for posting their comment or I would have been scammed.
