The 39-year-old admits she needs to make a few improvements to ensure selection for what would be her sixth Olympic Games.
"I'm going to be working really hard over the winter months to make sure I'm here next year, said Williamson.
"I'll be making choices over equipment this winter but also working hard technically with the coaches, psychologists and strength and conditioning teams - it would be so special to compete at a home Games."
