Douglas finished third in Brisbane last weekend in a meeting won by Morris and is aiming to turn the tables.
Both riders have expressed a desire to return to Parrys International Wolves for the 2021 season subject to it starting in April.
Douglas said: “It was good to get a meeting under my belt in Brisbane and I felt pretty good.
“ I’ve been out on the bike practicing a few times but nothing beats racing against three other riders.
“When the tapes rise you always switch to race mode and that is so much better than having a skid on your own
“North Brisbane is my local track and I’ve done plenty of laps around the place. I was a little disappointed with third place in the final but I’m looking at the bigger picture of this weekend and winning the Queensland title.”
Douglas enlisted the help of former Poole favourite Davey Watt in Brisbane.
“I want to thank Davey who was on the spanners for me,” he said. “He’s always offering so much advice both before and during the meeting.
“He can see what I’m doing wrong at times and is always there to offer advise on how to change things. He really has been a big help and I can’t thank him enough for giving up his time.”
Also in the meeting tonight is Sheffield’s Josh Grajczonek, Poole’s Zane Keleher and Ipswich man Jake Allen.
