Daicos has had a light week of training since receiving a knock to his lower leg during the Magpies' convincing win over Melbourne on Monday.
But the Brownlow Medal fancy passed a fitness test on Friday, running at full pace and taking part in football drills with his teammates.
He has been given the green light to take on the Kangaroos at Marvel Stadium on Sunday.
"He's good to go. He'll play," McRae said.
"We played Monday, so we didn't do anything on Wednesday with him.
"Today was an opportunity to get out and move. He went really well and he'll be right to play."

McRae said Oleg Markov is in a "race to the line" because of a jarred back, with lightning-quick defender Tew Jiath on stand-by.
Jiath, the younger brother of Hawthorn's Changkuoth Jiath, has been named among the Magpies' emergencies and is a chance to debut.
The 19-year-old was selected with pick 37 at last year's draft.
"I just love the way that he expresses himself on the footy field," McRae said.
"He goes for his marks, much like his brother from Hawthorn, and he's a serious talent.
"He's going to be a really nice player for us."
North Melbourne have been buoyed by last week's breakthrough win over West Coast, and defender Charlie Comben boldly declared Collingwood "really, really gettable" in a radio interview ahead of Sunday's clash.
The Magpies, who are battling a host of injuries, in particular through the midfield and forward-line, have lost just once since round three.
The contest pits McRae against Kangaroos coach Alastair Clarkson for the first time, after the pair worked together for a year at Hawthorn in 2021.
"I don't think any game's an easy win. We respect our opposition enormously," McRae said.
"I worked with Clarko for 12 months and he's an incredible coach.
"I know what sort of fire he has in the belly for these sorts of games and I'm sure they'll take a lot of things away from us - as we'll try to do to them."
