Deadly detail hiding in plain sight in this Sydney garden

Residents in a newly developed suburb were left horrified after they discovered an eastern brown snake lurking in their front garden.

The massive six-foot long reptile was spotted slithering across the front of several properties in Marsden Park, in Sydney 's north-west, on Sunday afternoon.

Terrified locals inundated local snake catcher Chris Williams with panicked calls as they kept a close eye on the deadly discovery.

'There was three successive calls within the space of two minutes,' Mr Williams told Daily Mail Australia.

'There were some very anxious people trying to get me on the phone'.

Mr Williams said residents had seen the snake crawling around the front gardens of several properties.

The creature was found sheltering itself on the side of a garden bed at the front of a home a short time later.

Mr Williams said the reptile, which is the second most venomous snake in the world, was 'quite thick' and 'intimidating'.

'It's probably the largest one I've caught so far,' he said.

Mr Williams worked quickly to remove the snake from the garden of the home before he placed it into a bag.

He said a large group crowd had gathered on the street to monitor the whereabouts of the creature.

'Once it sort of calmed down and stopped moving around, the whole street had eyes on it,' Mr Williams said.

'When they realised it wasn't going any further, they all got to know each other so the snake acted like an ice breaker for the street'.

Mr Williams, who runs Urban Reptile Removal, said snakes can often pop up in residential areas.

He said local wildlife often get displaced when areas are redeveloped at a large scale.

'Eastern browns have become really good at cohabiting in urban and semi-urban environments and they're main diet is mice,' Mr Williams said.

'Where people are mice follow so there's just this attraction for eastern brown's in urban areas'.

Marsden Park was first identified as a residential area in 2013.

More than 33,000 homes are expected to be built in the area by 2026.

Around 250,000 people are expected to live in the suburb once it is fully developed.

Mr Williams urged people not to scare a snake away if they spot the creature lying in an area where they live.

He said this will prevent the reptile from scurrying off and it will make it harder for snake catchers to remove it from the area.
