The road races for the 23-30 September championships to be broadcast and streamed live on SBS will be held on a hilly circuit that Cycling Australia technical director Brad McGee calls "super tough".
"We know the course is going to be super tough and feel confident we have the right mix of talent and purpose for this event," McGee said.
“We started this process thinking about how to win these races. Then we worked back from that endpoint and considered which riders had the capabilities to deliver on that strategy."
After last year's selection controversy, selectors have filled all the available berths for the women's road race team.
Amanda Spratt will lead the elite women's squad which includes Grace Brown, Brodie Chapman, Tiffany Cromwell, Shara Gillow, Lucy Kennedy, and Sarah Roy.
Richie Porte and Rohan Dennis headline the elite men and will be joined by Simon Clarke, Jack Haig, Chris Hamilton, Damien Howson, Robert Power and Rory Sutherland.
Porte is targeting the road race after a tilt at the 2018 Vuelta a España where he hopes to make up for his Tour de France disappointment when he crashed out for the second year in a row.
Spratt is in career-best form and will lead the women's road team, while Dennis is a perennial medal contender in the elite men's time trial. The retirement of Katrin Garfoot means there will be no Australian starter in the women's elite time trial.
“From the moment the course was released, we have been thinking about how to best perform this year," Australian Cycling High-Performance Director Simon Jones said.
"The team has developed the best possible strategy and the selections were made to support the key objective of maximizing the chances of winning.
"From a selection process perspective, we have moved to an earlier selection timeframe to give all athletes time to prepare and think about their roles and where applicable do specific work.”
Lucas Hamilton and time trial specialist Callum Scotson also headline a powerful men's under-23 team with Jai Hindley, Robert Stannard, Michael Storer and James Whelan rounding out the selections. Scotson will ride the time-trial.
The junior squad was named earlier in the year and will include national champions Sarah Gigante and Tyler Lindorff.
