EXPOSED: The REAL way TikTok comedian correctly 'predicted' Sydney's Covid numbers for five days and how you can do it too - and it has nothing to do with maths like he insists

A TikTok comedian who shot to fame by predicting NSW's daily new Covid case number five days in a row insists he does it with maths skills.

Jon-Bernard Kairouz's incredible accuracy prompted speculation he had a source inside NSW Health feeding him information, which he denies, prompting a 'witch hunt' by bureaucrats.

But there is a much more convincing explanation right under everyone's nose using an app you completely forgot about.

The federal government's Coronavirus Australia app, created last year to provide details about pandemic but never took off, holds the key.

The federal government's Coronavirus Australia app, created last year to provide details about pandemic but never took off, updates all state case numbers - total since the pandemic began - around the country about 8pm every day - subtract one from the other for the new cases

The app updates all state case numbers - the total since the pandemic began - around the country about 8pm every day.

The following day's case numbers can be easily obtained by simply subtracting the previous day's number from the new one - the only maths required.

Sunday night's number of NSW is 6,942 compared to Saturday's 6,833 - meaning the number to be announced at 11am on Monday is 109.

This is the same number Mr Kairouz 'predicted' on Sunday night - tellingly not long after 8pm when the Coronavirus Australia data dropped.

The prankster claimed on Channel Ten's The Project on Sunday he and his brothers calculate the figures by using the 'Kairouz probability algorithm'. 

Jon-Bernard Kairouz (pictured on The Project), who refers to himself as the People's Premier, has correctly predicted the state's soaring case numbers for the past five consecutive days.

When pressed by the show's host Jan Fran about how he does it, Kairouz said it just comes down to simple maths.

'We are quite lucky as not all complex calculus has one given solution, but we've been lucky to get five in a row and we could possibly get Michael Jordan numbers tomorrow,' Kairouz said, referring to the US basketball great's six championships.

In his viral social media clips, Kairouz is often seen drawing nonsense diagrams, statistics, and equations on a whiteboard before giving his eerily accurate predictions.

'The diagrams are called homoeomorphic irreducible trees and that is combined with all the other variables we include such as the diameter of Fairfeild and the circumference of southwest Sydney,' he told the panel while holding a gold wrestling belt over his shoulder.

'We also take into account the infectious community cases and then we can deduce a concrete figure we are happy to push out to the public.'

Gladys Berejiklian was pressed about the young TikToker's numbers at a press conference two days ago

Fellow comedian and host Tommy Little admitted he's a big fan of the young man's shtick.

'I love the belt and I love the People's Premier,' Little said.

'I think we can all agree you are full of s**t on this maths thing but to be honest I don't care.'

Two days earlier Gladys Berejiklian was questioned at a press conference on whether NSW Health had a leak and if she was concerned.

'I know at the moment a lot of people alleged to have various bits of information and that's welcome, we are in democracy,' she said.

But as the speculation grows about how he's able to come up with his seemingly magic numbers, Kairouz said he's just trying to enjoy the process and his new-found notoriety.

'I'm having a ball,' he said.

'I've been creating content on Instagram and TikTok for just about a year now and to grow exponentially on the social platforms has been really fun and it's been a whirlwind of a week.'

He says he will make his sixth successive prediction Sunday night. 

Online sleuths have been desperately trying to figure out how the TikTok prankster makes his predictions.

He makes the prediction around 10.30pm most nights.

NSW Health officials collate each day's number of positive cases up until 8pm - giving him two-and-a-half hours to hear from any source.
