Hollywood star Kate Walsh shares surprise at passing huge Mad Max-style truck in Australian outback: 'Am I driving into another dimension?'

Kate Walsh has lived in Australia for six years, but the Hollywood star is still adjusting to the peculiarities of her adopted homeland. 

The American actress detailed a recent trip across a desert road in Perth, Western Australia on her Instagram page, filming a terrifying-looking truck in front of her car. 

The massive vehicle looked very much like something from the dystopian Mad Max films, covered in wires and spikes and adorned with an 'oversize' placard. 

As the unusual truck pottered down the country road, the 58-year-old filmed it and shared her bemused commentary.  

'Often in the country whilst driving in Australia you get stuck behind oversized vehicles,' she said in the clip.

'I've never seen one that is this oversized.... it was like, "Is that a movie, is that like a moving story, is that a play on a truck, is it a Dr Seuss book come to life?"'

Kate said that despite the scary appearance of the truck, the driver was quite courteous. 

'I will say the gentleman in the oversized vehicle was very kind. He kindly pulled over and let me pass,' Kate explained.

'But boy, it was a treat... I was like, "Is this where the timeline split, am I driving into the matrix, like the other dimension?"'

'I hope you're as amused by it as I was,' she concluded. 

Despite her Hollywood career that saw her rise to fame on the hospital drama Grey's Anatomy, Kate has called Australia home for some time. 

The actress relocated to Perth, Western Australia in 2020 after getting engaged to Western Australian farmer Andrew Nixon.

She recently revealed she had fallen in love with Australia's laid-back lifestyle and was happy to call Perth home.

'I really love Western Australia… I think nature here eclipses everything. It drives me,' she told news.com.au. 

'I like the slowness. It's really good for me. And then you go back overseas and you're like, "Oh my god. People are insane",' she added.

Walsh then said she often flew to America for filming and then returned to Australia when she was free to spend more time with her fiancé.

'I feel very fortunate I can pop back to LA, go to work, and then come back here and live my best life.' 

'I needed my life to be a lot more balanced. And then, I fell in love with an Aussie, and here I am. I love it. I'm very grateful,' she added.

The California native reportedly met Andrew, of Nixon Farming, on a cruise just before the start of the coronavirus pandemic in early 2020.

The Nixon family have been farming predominantly malt barley and canola in the Moora/New Norcia area of Western Australia for close to 100 years, according to their website.
