The Geelong guernsey was chosen as the club's strip and the "Rams" nickname adopted, in reference to the area's contribution to the early development of the wool industry in Australia.
Despite this rocky start, the Rams finished 3rd on the ladder in their initial season, but bowed out in the Preliminary Final, losing to Bankstown Sports.
Peter kicked the Reserve Grade record of 11 goals in the Round 10 game against Manly-Warringah, which stood until broken by Jason Ware in 2006.
The match on 1 May, against Macquarie Uni at Colbee Park, saw the Rams kick 35.30 (240), which still stands to this day as a record Reserve Grade score.
One highlight of the season was Senior Grade kicking its record score (to that time) of 34.14 (228) in the Round 10 match against Mount Druitt, with Chris Farrell booting 10 goals.
This move was taken to try to address the imbalance in the competition and also to make the Second Division somewhat geographically based - the other Senior Grade teams being Hawkesbury, Liverpool, Blacktown and Baulkham Hills.
Reserve Grade finished fourth and pushed Heathcote (who had beaten them easily in their final three Home and Away meetings) in the First Semi-Final to lose by just the straight kick.
Senior Grade finished second on the ladder, but bowed out of the finals in straight sets - losing firstly to top placed Hawkesbury and then to Bargo, where inaccurate goalkicking ultimately cost them the game.
The SFL 2 competition again fielded a representative side, this time against the Central Coast at Tacoma, with Geoff Eldering (Captain), John Oxley, Michael Walker and Alf Bradley playing.

On the 28th July, after the Rams had played a game, there was a car crash which took the lives of player Travis Hopper and club supporter Dianne Guymer.
The Grand Final rematch against Hawkesbury alas was unsuccessful, the opposition jumping the Rams in the first quarter and maintaining that lead for the rest of the game.
Captain-coach David Armstrong equalled the club finals goalkicking record by booting nine goals in this game, and capped off a great year by also winning the SFA's Snow Medal.
The senior sides showed promising results, probably the highlight being the club's first-ever win over Wollongong in both grades at Greygums Oval.
Penrith-St Clair lost their final home and away match of the season by three points, relegating them to fourth place on the ladder – a win would have gained them second spot.
Also prior to the season's start, the committee of the Greater Western Power voted to come under the umbrella of the Penrith club, meaning the Rams fielded an Under 18 side in its own name for the first time since 2002.
Senior and Reserve Grades missed out on the finals (each finishing sixth), while the Under 18s had a promising season interrupted by rain, which eventually saw them occupy fifth spot.
A major highlight of 2006 was the 25th Anniversary Dinner, held at Emu Plains Sporting and Recreation Club on Saturday, 29 July, with approximately 100 people in attendance.
The most successful of these was the Ramettes, now in the newly created Women's Division 2 competition, who won their First Semi-Final in extra time and bowed out of contention in the Preliminary Final.
Club administrator Greg Corless deservedly won the Sydney AFL Volunteer of the Year in recognition of his tireless work for the Rams.
Ramettes Renee Tomkins and Melissa Brydon gained selection at full-back and in the forward pocket respectively in the Sydney AFL Women's Team of the Year.

Mitch Stevens became the second Penrith player to kick 100 goals in a season, with 102 in Senior Grade, finishing runner-up in the Sanders Medal, two votes behind the winner.
First Grade finished one position higher in second spot, however won the Platinum Division premiership, defeating the Western Magic by 17 points.
Individual accolades where bountiful in 2018 with Auburn-Penrith Giants Renee Tomkins (also selected as full-back in the Premier Division Women's Team of the Year) and Haneen Zreika (also finished equal first in the Mostyn Medal as Best and Fairest in Premier Division but was ineligible due to suspension) being drafted by the Greater Western Sydney Giants AFL Women's side.
On the positive side, the Rams men's Senior Grade had a dominant season, losing just the three Home & Away matches to finish Minor Premiers.
Comprising a canteen, social rooms, office and storage space, the building was the latest of many improvements made to Greygums over the years, making it a superb facility for Australian Rules football in Penrith.
The Rams, finishing in third spot after the H&A series, defeated Balmain in a hard-fought semi-final and met Southern Power in the Grand Final at Rosedale Oval.
Again, it was the Ramettes who flew the flag for the club, finishing third after the Home & Away rounds, and making it through to the Preliminary Final - losing to eventual runner-up Newtown.
Four time premiership player Jay Edwards was appointed as Senior Grade coach, while Dave Sanders took over the reins of the Ramettes from Nathan White.
