Amazing Dream is a Kiwi horse who raced for 8 months in Aussie on her way here. She was trained by Mark Purdon in NZ and his son Nathan trained her in Aussie. She will do really well here, she is top class and like you say, beat the boys often.
Last year she was racing against Copy That and Self Assured who are the two best older horses in NZ.
Watch Me Now who is in the same qualifier for Alagna beat her once in NZ as well.
She was foaled in NZ in November 22nd 2016 so she really is only 5 but of course turned 1 year old 40 days after she was born if you go by our time here
