While Scotson looks to defend his title, the 23-year-old is just one part of a formidable BMC line-up with Richie Porte, Simon Gerrans and Rohan Dennis all confirmed for the event.
"It will be nice to go into the road race with numbers," Porte said, himself a bronze road medal winner in 2012 and 2014 behind new team mate Gerrans.
"With the numbers that we have, four strong guys, I believe we have the guys to do it.
"If it's not me, to have someone of the calibre of Simon come join the team in 2018, Rohan is always up for a good fight and Miles showed last year he could do it."
Garfoot, who will swap the Orica-Scott kit for Queensland Academy of Sport colours, predicts an interesting tussle for the women's road race title.
"Leading into Commonwealth Games, it will be big. It will be very hard (in 2018) to defend because of this, riders want to qualify for the Games.
"I think that I will be well covered in the race and not being part of the Orica team means I will have a few more high quality opponents." These Orica opponents include Amanda Spratt, Jessica Allen and Sarah Roy.
Like Dennis, Garfoot will also look to top the time-trial for a third straight year, but Shara Gillow, Cameron Meyer and Luke Durbridge are all confirmed to try and upset that party.
The FedUni Road National Championships action kicks off as usual with the critierium on 3 January but the 2018 event also adds an U19 and para cycling race to the line-up.
"The green and gold stripes are an honour to win and wear," said triple Paralympic gold medallist Carol Cooke. "Not many people can say that they have won them, so I wear them proudly.
"And it is even more amazing the para-cyclists now have to chance to battle for them at the road nationals for the first time."
Details on the broadcast schedule for the 2018 FedUni Road National Championships will be announced in the coming weeks.
