Lachie Neale's new flame Emma Field braves the rain to do a coffee run for the couple ahead of AFL Grand Final clash between Brisbane and Fremantle

Brisbane Lions' newest WAG Emma Field was seen braving the rain on Saturday morning just hours before boyfriend Lachie Neale plays in the AFL Grand Final.

Neale, 33, will clash against Fremantle at 2.30pm AEST after he successfully appealed the one-match ban that almost dashed his premiership dream.

Field, 29, played the part of dutiful partner ahead of the big game as she stepped out into the poor Melbourne weather to do a coffee and food run for the couple.

The brunette beauty rugged up in an oversized pink jumper, pulling the hood up over her long tresses as she stepped out without an umbrella. 

She paired it with very form-fitting black leggings which flared over her matching sneakers.

Field later hid her eyes behind a pair of designer sunglasses as she was seen carrying two takeaway coffee cups and a burger box. 

At one point, she was spotted chatting with someone on the phone.    

Neale and Field were all smiles on Friday when they were seen enjoying a relaxed brunch date in Melbourne after he won his appeal against a one-match suspension that threatened to end his premiership dream. 

With his place in Saturday's decider secured, the two-time Brownlow medallist laughed and chatted with his partner during a break from the grand final build-up.

The couple headed to a nearby cafe and sat outside, where Neale tucked into a burger before they walked back to the team hotel.

Neale planted a kiss on Field's head along the way, with the pair continuing to smile and chat before he stopped to sign autographs for waiting fans.

Their outing came two days after they were photographed holding hands during a coffee date in Brisbane, when his grand final hopes were still hanging in the balance.

By Friday, that uncertainty had lifted but the controversy followed him to the parade.

Fremantle supporters booed and heckled Neale as he travelled through Melbourne's sporting precinct alongside teammate Ty Gallop.

The jeers were also heard during his interview with Lions great Alastair Lynch, with Dockers fans outnumbering Brisbane supporters along the route.

Asked whether he had feared he was in trouble during the week, Neale gave a frank response.

'Most of the week, really. You're never really sure how these things are going to go. Very happy that it's gone my way,' he said.

Neale had initially been handed a one-match suspension for striking Hawthorn's Jack Ginnivan during their preliminary final.

The tribunal upheld the penalty on Tuesday after a hearing lasting four-and-a-half hours, before Brisbane successfully appealed on Thursday.

Speaking on Friday, Neale credited those closest to him with helping him through the uncertainty.

'I've been okay. I've got great people around me that keep things pretty normal, other than having to attend a couple of tribunal hearings. Just glad I'm able to play tomorrow,' he told Fox Footy.

Saturday's clash with his former club could also be his Brisbane farewell, with Neale bound for Collingwood next year.

First, he has a third consecutive Lions premiership in his sights.

'We've shown in previous finals, this year and in the last couple of years that we're never out of it - and we truly believe it in every situation,' Neale said.

'We'll draw on those experiences tomorrow for sure.'
