AFL Round 18 Preview & Predictions

Round 18 opens with a top-two showdown between ladder-leading Fremantle and Sydney in Perth, with Carlton's seven-game streak, a GWS-Geelong coin-flip and the in-form Brisbane Lions also on the card.

Round 18 opens with a heavyweight top-two showdown — ladder-leading Fremantle hosting Sydney in Perth — and there is plenty riding on the rest of the card. Catch up on Round 17 results first: GWS ended Fremantle’s 14-game streak, St Kilda buried Essendon, and Charlie Curnow seized the Coleman Medal lead.

Fremantle still top the premiership market from Sydney, with a logjam of contenders behind them — and Carlton carrying a seven-game winning streak into the MCG. Below are our Round 18 predictions and head-to-head reads for every game; model your run home with the AFL Ladder Predictor.

Fremantle vs Sydney

Fremantle to win by 1-12 points

The round opens with a genuine top-two showdown at Optus Stadium. Fremantle (14-2) still lead the ladder but arrive stung — their club-record 14-game winning streak was snapped by GWS last week — while Sydney (13-3) sit second and blew the Western Bulldogs away with a six-goal opening burst.

The Dockers are strong home favourites (around $1.90) at a genuine fortress, but the two best sides in the competition rarely blow each other out, and Sydney welcome Tom Papley back from a calf. Freo are without Hayden Young (groin) and rest Sean Darcy, lifting Caleb Serong’s midfield load. We lean Fremantle to reset with a tight win inside two-and-a-half goals; Sydney on the plus line is the safety play.

Collingwood vs North Melbourne

Collingwood to win by 13-39 points

Collingwood return to their Marvel Stadium deck off a gritty six-point win over Gold Coast, Nick Daicos again enormous (31 disposals, eight clearances) and Scott Pendlebury back from a calf to add polish. North Melbourne, chasing a lower finals berth, pushed hard before falling to Port last week but lack the forward firepower to trouble a settled Pies outfit over four quarters.

Collingwood are clear favourites; back them to win comfortably, with Daicos a strong bet to pile up 30-plus disposals again.

St Kilda vs Port Adelaide

St Kilda to win by 1-12 points

A low-scoring grind between two sides chasing the lower finals places. St Kilda thumped Essendon by 67 last week and already have Port’s measure this season (an 81-67 win at Adelaide Oval), with Nasiah Wanganeen-Milera in extraordinary touch — a career-high 46 disposals last round and six straight 30-plus games. The Saints are without co-captain Jack Sinclair for the rest of the season (calf), but Port’s own injury list is long and their scoring modest.

Expect a tight Saints win rather than a blowout; the under on total points appeals given both defensive styles.

GWS vs Geelong

GWS to win by 1-12 points

The round’s true coin-flip. GWS are coming off their best win of the year — a 21-point upset of Fremantle powered by Jake Stringer’s career-high seven goals — and have won the last four meetings with Geelong at their Showground fortress (by 26, 4, 4 and 7 points). Geelong, by contrast, have managed just one win in five and are wobbling on the road.

The models narrowly favour the Cats on paper, but venue, form and the head-to-head edge tilt us to the Giants in another tight one — Stringer to kick 2+ goals is the standout multi leg.

Carlton vs Hawthorn

Hawthorn to win by 1-12 points

Under Saturday-night MCG lights, in-form Carlton — a seven-game winning streak under interim coach Josh Fraser — meet a Hawthorn side that slipped to a 35-point loss to Melbourne but still holds third. The Hawks are favourites (around a 12.5-point line) and could welcome back several stars, with a debut for Ollie Greeves.

Carlton’s streak is real momentum and this shapes as a genuine contest: we lean Hawthorn to win it, but Carlton +12.5 is the value play for a side this hot.

Adelaide vs Gold Coast

Adelaide to win by 13-39 points

Adelaide, locked in a top-four scrap on 10-6, host a Gold Coast side that has lost six straight and has never won at Adelaide Oval (0-13). The Crows are close to full strength, with Wayne Milera and Riley Thilthorpe back in the mix, and their midfield class through Jordan Dawson and Izak Rankine should prove decisive.

The Suns have been competitive (six points off Collingwood) but a loss here all but ends their finals hopes. Back the Crows by three-to-six goals, and watch Ben King (43 goals) keep the Coleman Medal race warm.

Western Bulldogs vs West Coast

Western Bulldogs to win by 13-39 points

The Bulldogs, clinging to eighth, host the cellar-dwelling Eagles, who have lost 11 straight at Marvel Stadium and travel poorly. Everything points to a comfortable home win — models project a 30-to-35-point margin.

The one caveat: the Dogs make five changes and have Tim English (ruck) named under an injury cloud, which could tighten it. Marcus Bontempelli drives the midfield; back the Bulldogs on the line, with Aaron Naughton an anytime-goal option.

Melbourne vs Richmond

Melbourne to win by 13-39 points

Melbourne (10-6) can’t afford a lapse in a classic danger game against a rebuilding Richmond, having won the last seven meetings by an average of around 30 points. The Demons blew a huge lead against Hawthorn last week before holding on — a warning against expecting a rout — and the Tigers keep games close, losing to Carlton by just two.

Jacob van Rooyen (five goals last week) leads the Melbourne attack, though Bayley Fritsch faces a fitness test. The Tigers +30 has appeal given their pattern of narrow losses.

Brisbane vs Essendon

Brisbane to win by 40+ points

The Lions close the round as the competition’s form scoring side — four straight wins at around 117 points a game — and are bolstered by the returns of co-captain Hugh McCluggage and veteran Dayne Zorko. Essendon (1-15) arrive off a 67-point hiding from St Kilda and have been thrashed repeatedly; the market has Brisbane odds-on at around $1.02.

Back the Lions to win big at the Gabba; a Brisbane team-total over and a Josh Dunkley disposals line are the plays.
