The Shepparton teen finished in a tie for sixth at the Cranbourne Golf Club-hosted event, nine shots behind eventual winner Joshua Robards (Newcastle).
While Goodall had raced out of the blocks with a par 72 first round, he could not maintain that hot pace for all three rounds of the tournament, with 18 holes shaved off the event due to Tuesday's intense smoke haze.
He shot a four-over 76 on Wednesday to slide down the leaderboard, but he came out firing on Thursday with birdies on the first two holes to get things rolling.
But Goodall would bogey three of the next four holes before completing a par back nine to shoot 73 for the day and finish the tournament five-over.
In his under-16 boys category, Goodall finished in an impressive tie for fourth, still seven shots behind the winner.
Kyabram's Cooper Gentle also put his best foot forward across the 54 holes, finishing at eight-over in a tie for 11th.
Gentle also hit the second round even on the scorecard, but double-bogeyed consecutive holes to leave himself plenty of work to do.
The Rich River member shot 78 on Wednesday before getting back in form with a two-over 74 Thursday to come close to a top 10 finish.
And Yarrawonga's Baxter Droop, who plays football for Picola District league club Rennie, could not stick with the competition's leaders as things progressed.
After a one-over 73 for the first round, Droop shot 80 and 76 in the next two batches of 18 holes to finish 13-over and in a tie for 23rd.
