Miller's contract with Marc VDS Honda was set to expire at the end of the year, with plenty of talk surrounding his next move. 

Pramac Ducati were the favourites to land his signature, and the switch was finally made official on Thursday. 

Miller will replace Scott Redding at the satellite team, joining Danilo Petrucci for the 2018 season. 

The 22-year-old becomes the first Australian to ride a Ducati in MotoGP since Casey Stoner back in 2010, barring Damian Cudlin's one race fill-in in 2011.
