Travelling on the campaign buses of our political leaders gives you a curious insight into Australian democracy.

They almost never meet anyone who hasn't been carefully vetted beforehand. Journalists have no idea where they're going until they arrive at a location.

Everything is tightly scripted and choreographed to deliver the leaders' messages to a weary and distracted public.

We joined this political mystery tour to get an insight into this high-stakes theatre, but more importantly to try to get answers to the questions that matter to Australians:

What can be done to address housing affordability? Is there relief from rising cost of living? What does a chaotic and uncertain world mean for Australia?

We also spoke to those who've seen up close how Peter Dutton and Anthony Albanese operate, and who've followed their campaigns' highs and lows.

We do a deep dive into their histories and reveal new details that have never come to light.

With less than a week to go, Four Corners takes you beyond the talking points and the spin, to examine the leadership records of Anthony Albanese and Peter Dutton. And their plans for the nation if they win.

We love Bunnings — it's where we go for our weekend sausage sizzle and to fulfill our DIY dreams.  

But what if the store Australians trust most is not as benign as it would have us believe?  

Bunnings has quietly become one of Australia's most dominant and profitable retailers, with rivals saying its market power matches Coles and Woolworths combined.   

Yet it faces none of the scrutiny of the big two supermarkets.  

Critics also claim it's a corporate predator systematically picking off independents, shutting down competition and abusing its dominance with suppliers. 

For its part Bunnings insists it's just another competitor in a crowded field.  

Four Corners' Angus Grigg and Emilia Terzon from the ABC business team dig into Bunnings' unchecked dominance, its soaring profits, and whether regulators have turned a blind eye while it reshapes Australian retail.  

This is the untold story of how Bunnings became a national icon — and what we lose when one brand dominates the backyard.
