"Ian took me out in a speedboat first off and there were plenty of white caps - it looks a little bit dodgy," Crow said of the conditions yesterday.
"It's my first time on a tidal track and quite a bit different to the lake courses I'm used to."
Crow is from Melbourne, but is based in Canberra where the Australian national squad trains. She has also rowed with success at Lake Karapiro in Waikato.
During the 2010 World Rowing Championships at Lake Karapiro Crow won silver in the double sculls and finished fourth in the quad sculls.
"I had a couple of months off after London and have been back on the water for the past few weeks. One of the Aussie girls who has previously competed in the Billy Webb told me about it in London and I was happy to enter. It will be a very good practice run for the long distance time trials in Sydney the weekend after the Billy Webb.
"I'm looking forward to the challenge this weekend and hope the wind drops a bit. If it doesn't it's a good thing I can swim," Crow said.
Crow will face New Zealand Olympic quad members Fiona Bourke and Sarah Gray, who was a member of the Aramoho club when she rowed for Wanganui High School.
Also in the Billy Webb are New Zealand summer squad members Genevieve Armstrong and Zoe Stevenson.
Weenick said coming from a quad team to single sculls was a major transition and Crow's experience in the singles was likely to tip the scales in her favour this weekend.
