The victory followed wins over Collingwood and Port Melbourne over the previous two weeks, making it the first time since rounds seven, eight and nine of 2007 when Matthew Knights was coach that the Bombers have strung together three consecutive wins.
Bendigo now sits in fourth position on the ladder with a percentage of 121.74.
The Bombers made a strong start to the contest, opening up a 18-point advantage at quarter-time as they led 5.2 to 2.2.
“We started well and used the ball well going into our forward 50 in that first quarter,’’ Bendigo coach Shannon Grant said.
By half-time Geelong had closed to within eight points after holding the Bombers goalless in the second quarter.
The third term remained an arm-wrestle before a goal to Michael Still on the three quarter-time siren gave the Bombers a 13-point buffer entering the last quarter.
The Bombers kicked 6.2 to 3.2 in the last quarter to secure the crucial away victory.
“With our second halves, we have really been running the games out well,’’ Grant said.
“The win is a credit to the boys because they had to work hard, they shared the load well and they have been running over the top of teams, which is good.
“Getting these early wins become really important as the year goes on, so this is a great result.
Still was the Bombers’ leading goalkicker with three.
The Bendigo side also included 2008 Hawthorn premiership player Mark Williams.
Playing up forward, Williams kicked two goals to be among 10 Bendigo goalkickers.
Geelong’s best players included Nathan Djerrkura, Ryan Gamble, Ben Raidme, Ben Johnson, Daniel Jull and Allen Christensen.
There was one report in the match, with Geelong’s Daniel Menzel booked for charging Howlett in the third quarter.
The victory squared the head-to-head ledger between the Bombers and Geelong at six apiece, with the win Bendigo’s first at Skilled Stadium since 2004.
