Jess and Sarah Hosking will be making AFLW history on Sunday but are just "trying to keep things as normal as possible" in the lead-up to Carlton's grand final clash against Adelaide at Adelaide Oval.

The 23-year-olds will be the first pair of twins to play in an AFLW grand final together, and will join a tiny number to have played in any AFL grand final, including Geelong players Alistair and Stewart Lord in 1963 and and Brisbane Lions Chris and Brad Scott in 2001 and 2002.

This Sunday will also mark Carlton's first grand final since 1999. Understandably, the pair have "a few little nerves".

"It's very unique and sort of surreal, it hasn't quite hit us yet," Sarah said.
