Batting first, the Bushies got their semi-final off to a great start thanks to a 70-run stand from Luke Dunne and Jack Fullager.
Despite the loss of three quick wickets, the young Bushrangers kept their heads and managed a respectable 7/154 from their 42 overs.
Fullager top scored with 53, while Dunne made 42.
Jasper DeFazio and Henry Sadaya made 14 each and Deakyn Kohler made 12.
Yarrawonga-Mulwala started its run chase shakily when Sadaya bowled one of their openers with just eight runs on the board.
Sadaya and Matt Knight combined well for the opening spell and kept the pressure on the Yarrawonga batsmen.

They were eventually bowled out for 109 in the 35th over.
Fullager and DeFazio took two wickets each, while Grayson Kirk got a wicket to close the game out.
