Storm lock Dale Finucane in the 2016 NRL grand final.

Manly fullback Tom Trbojevic and Storm lock Dale Finucane have joined the NSW Origin camp ahead of Wednesday night's State of Origin series decider.

Tom Trbojevic, who had previously been involved in camp for Game Two, as well as Origin III 2016, returns to the extended squad ahead of the decider, while the Melbourne Storm's Dale Finucane joins the squad for the first time.

"I'm really excited. I found out after the Parramatta game at about 11 o’clock and came straight into camp," Finucane told NSWRL.com.au.

"To be here is really exciting for me and something I'm really proud of."
