Elliott struck his 28th first-class century at the Melbourne Cricket Ground on Monday to help steer Victoria to 331 for eight before captain Darren Berry declared. The tally gave Victoria two first innings points as they cruised past South Australia's first innings total of 225.
Victoria, which last won the domestic four-day title in 1990-91, is now 12 points clear of second-placed Tasmania but Elliott vowed the team would continue their aggressive approach in pursuit of outright wins, which earn six-points.
Barring a disaster of monumental proportions, they will now host the final at the Melbourne Cricket Ground.
"We've talked about the final but I think we really need to just keep playing for six points, and keep playing to win games," Elliott said. "That's why we've been so good this year, we've always found a way to win games and we need to keep doing that into the final ... we can't take our foot off the pedal."
Elliott played anchor role to Brad Hodge at the start of the day and then to Jonathan Moss who made 46 in the middle before opening his shoulders with the support of Berry and Mick Lewis, who both made 16.
The tailenders offered valuable support after Shaun Tait, who took 3-55, hit back for South Australia with three wickets in three successive overs before tea.
