The Viski family, who live at The Rock, will be one of the many people taking on the one-bucket challenge for the inaugural Water Night on Thursday.

Between the hours of 5pm and 5am, households are encouraged to avoid turning on their taps for one night in an effort to make Australians aware of how often they use water. Instead, residents will use a single bucket of water for everything but handwashing, drinking and flushing.

Mrs Viski said keeping their water use to a minimum as part of their everyday routine was a hot topic of discussion in her household.

"My seven-year-old daughter Matilda and I have been talking about conserving our water usage for so long," she said.

"But as she has gotten older we try and do the best we can to educate her about what water goes into that one might not normally think about, like the making of clothes.

"Obviously we cannot control that, but we can look at how to save water at home.

"We all need to do what we can given the climate crisis we are in and the population is increasing at an exponential rate ... if we are able to sustain our population growth and feed everyone adequately, then we need to do what we can at home [through] small steps like participating in initiatives like this."

Research by Smart WaterMark found that despite being the world's driest inhabited continent, Australia is on autopilot when using tap water. Chief executive Chris Philpot said turning on the tap has become "second nature" for many people and a hard habit to stop.

Mrs Viski agreed, saying incidental water use will be the most challenging habit for the night ahead.

"I think it's important to be mindful of those incidental times we touch our tap when we might not need to," she said.
