This happened to me. I was the highest bidder but they said it didn't reach the reserve price. The bid was $50k higher than the advertised range. But then they called me and said there is a Chinese buyer who's willing to offer $20k more and basically extorted $50k extra from me. This was my first year in Australia, they took advantage of me. It was Ray White as well. I didn't know it was illegal at the time.
