"Defending at my home course carries a bit more meaning, and with that, I feel more responsibility to perform for them.
"It would be the dream to have the likes of Josh Geary, Mark Brown and myself playing in the last group which would be so cool for the club."
Toomey was also the defending champion at the DVS Pegasus Open last week where he finished in a credible tie for seventh.
He said experiencing the emotions of defending his title last week will put him in good stead for his home title defence this week.
"I would love to say I'm going to treat this like any other week, but I don't think it will be that way for me.
"With that extra hype and expectation that I have put on myself, hopefully, I can channel that energy in the right direction and stay out of my own way.
"I have a few new additions to the bag which will be a huge help. We had great conditions last week to test the new equipment. The game is in good shape and I think this week will be a story of how well I can handle myself."
A win would see Toomey join an elite group of golfers who have won three or more times on the Jennian Homes Charles Tour.
Daniel Hillier joined the group with his win at Pegasus last week and will be another golfer who is sure to feature come the weekend.
Round one begins at 7.30am today.
