In Bankstown, the classic Australian breakfast can be called one of three things - a 'bacon and egg roll', 'beef bacon and egg roll' or a 'rasher and egg roll'.

While all three dishes sound similar, only one actually contains pork.

A trip by Daily Mail Australia to the western Sydney suburb found there's a reason for this, with one cafe owner admitting locals are 'a bit picky... with pork'.

A trip by Daily Mail Australia to the western Sydney suburb found that there's a reason for this, with one cafe owner admitting locals are 'a bit picky... with pork'

The Bankstown local government area has a population of around 182,000 people, according to the 2011 Census, with a high proportion of migrants and first generation Australians whose parents were born in Lebanon or Vietnam.

While Catholicism is the the prevalent religion in the area, the second largest faith is Islam, with 19 percent of residents calling themselves Muslim - more than 11 times the national average, according to the Census.

The Koran forbids Muslims to eat pork.

Like many trendy areas in Sydney, you might expect the city's west to be hooked on the smashed avocado on toast phenomenon.

But on first glance, it would seem that bacon is rather unusually, the pick at brunch.

In the heavily halal conscious society, rumours were rife that even takeaway giant McDonald's refused to serve the real deal.

But a trip to three of the fast food chain's restaurants quickly proved this to be false.

However a journey down one of Bankstown's busiest streets quickly revealed there was truth to the rumour.

When Daily Mail Australia ordered a 'bacon and egg roll' from one eatery, the owner asked: 'Have here, or take it away?'

There was no mention the only 'bacon' available was not actually pork, but instead a beef alternative.

But on closer inspection, it can be seen that a cafe menu advertises a 'BBLT - with beef bacon, crisp lettuce, melted cheese and aioli'

'A lot of people come in and ask for a bacon and egg roll. I tell them it's beef. Some leave but the majority just get it,' a cafe owner admitted

The café owner eventually explained there was a 'beef bacon egg roll' on the menu and the only meat it contained was smoked, thinly cut beef.

Daily Mail Australia: 'So it's not actually bacon?'

Café owner: 'No, no. That's why it's beef bacon. It's from a cow, basically. It's beef.'

The cafe owner than admitted he would have served the 'bacon and egg' roll without telling the customer, had they not asked.

Claiming there wasn't much of a difference between pork and 'beef bacon', he then revealed why his cafe doesn't serve the more high-profile variety.

'No, no. No pork here. I don't have pork... maybe if I didn't tell you, you wouldn't notice. It's very nice,' he said.

The café owner later explained why 'bacon' did not have to be pork.

'If you look up the definition of bacon it is the process of how the meat is prepared,' he said.

'Pork is the cheapest. But there is beef bacon, turkey bacon, there's chicken bacon... there's probably horse bacon.

While Daily Mail Australia discovered bacon may not always be what you expect, some cafes do sell the more popular pork variety

The cafe owner then said that the decision to not sell pork bacon was a business one, and not because he was in Bankstown (pictured)

'The decision we made here is we will have beef. It's entirely a business decision. It's not because I'm in Bankstown.

He did, however, concede 'the area is a bit picky with pork.'

Another Bankstown café owner sells what he calls an 'egg and beef rasher roll' – no mention of 'bacon' - to avoid confusion.

'That's clearly beef,' he said of his product.

'The word bacon means a cut. It doesn't refer to pork. But people don't know that.'

'When they hear bacon they just automatically think pork so I took it out so I didn't confuse people.
