Australia have wasted little time in making their presence felt at the world para-athletics championships in London, with Cameron Crombie setting a world record in claiming the first event.
Competing in the F38 shot put for athletes with neurological impairments, games debutant Crombie threw 15.95m to smash the previous record mark by 37cm.
"I'm a bit lost for words. This is fantastic. I couldn't have hoped for a better result. I wouldn't have dreamt it," 31-year-old Crombie said.
"Being at the world championships, there's a bit more pressure than there is at home....
"The pieces came together today but I'm not sure if it's really sunk in yet."
Crombie who began his para-sport career in rowing, has made the most of his shift to the field events.
"I'm just going to try and enjoy this moment," he said.
"I'll never have this first time feeling again, but I'm looking forward to Saturday when I'll compete again in the javelin."
Another first timer, Martin Jackson, was fourth in the shot put on Friday.
"The Brits really get into it and make it what it is, which is a bit nerve-racking for a rookie but it's given me my first taste of competing for Australia, Jackson said.
Meanwhile, Rio Paralympian Deon Kenzie won his heat for the T38 800m in a time of 2.06:87, with the final on Sunday.
