NSW Blues stars shoot down State of Origin's biggest myth ahead of do-or-die game three in Brisbane

Reece Robson has labelled the so-called 'Queensland spirit' all talk, Jarome Luai is confused by the idea of its existence, and the mere suggestion of it flat-out frustrates Liam Martin.

And almost to a man, NSW players aren't sure the spirit up north exists any differently to what it does south of the Tweed River.

For as long as State of Origin has existed, the Maroons have claimed to have better understood the concept and to thrive off their so-called Queensland spirit.

It was seemingly built on Queensland going through hard times together, in a state where nearly 98 per cent of it is considered regional, rural or remote.

It has again popped up in this year's series, with coach Billy Slater repeating multiple times 'we're still Queenslanders' after questions following the Maroons' 38-18 loss in Melbourne.

But as far as the Blues are concerned, the 8.17 million people in NSW have every right to trumpet their state's spirit too.

'It frustrates you a little when they talk about all the tough times they go through,' Martin said.

'But I know from personal experience the tough times the Temora community has gone through.

'There is definitely a spirit in NSW as well. Hopefully we show that (on Wednesday).'

If any Blues player should know what the Queensland spirit actually entails, it's Robson.

He grew up a few kilometres south of the border in Tweed Heads, and has spent the past four years living in Townsville playing for North Queensland.

'I think everyone knows it's just all talk,' the Blues hooker said.

'They talk about Queensland spirit, but it's no different to NSW spirit. Everyone just wants to play (be it from NSW or Queensland).

'It's a bravado things for the fans to get behind, and they do get behind it very well. Obviously it's good for them.

'But for us, we make sure we're building the best spirit in our camp. The belief is there, and you just build your week as much as you can. Can't wait to get out there.'

Luai also heard Slater's 'we're still Queenslanders' comments, prompting a simple 'what is that?' from the NSW five-eighth.

But deep down he believes it is simply a buzz term the Maroons continue to tell themselves before every Origin, including Wednesday's Suncorp Stadium decider.

'I know there is spirit among this group as well,' Luai said.

'They can talk about their spirit up there in enemy territory. Behind closed doors every team has meaning behind words.

'That is obviously one to try and bring the group back together and bounce back from a loss. 

'But for us, we're focused on ourselves. We need to get what we get right, and then take it up there and do it.'

Kick-off at Suncorp Stadium is 8:05pm AEDT.
