A MAJOR family-owned supermarket in Perth’s northern suburbs will close its door next month, a victim of Aldi ramping up competition.

Sisters Supa IGA at Lakeside Joondalup Shopping City will close their doors by the end of June after almost 10 years.

Owners Peter and Cate Brodie, told the Joondalup Times they were “very sad” to be closing and a difficult decision came down to financial reasons.

“The influence of Aldi and the reaction of Coles and Woolworths to Aldi has been a factor,” Mr Brodie said.

Sisters was heavily involved in the community, including a ‘pay it forward’ scheme for customers to buy vouchers that enabled people in need to have a hot meal.

They also hosted a weekly morning tea for seniors. Mr Brodie said he hoped they could continue these events.
