BLACKTOWN police crime manager Detective Inspector Paul Tickner believes collecting your mail from 7-Eleven's new parcel lockers is probably more secure than your own letterbox.
"If someone wanted your mail, it's easier to steal from your letterbox where there's no CCTV," Detective Inspector Tickner said.
"A few years ago there was a spate of robberies from Australia Post holding boxes in the Mt Druitt [command area] but I haven't heard about that for a little while."
Detective Inspector Tickner said post office boxes were generally secure.
The Quakers Hill 7-Eleven store now has the parcel lockers, as do post offices at Stanhope Gardens and Baulkham Hills.
There are lockers in 100 locations Australia-wide, with plans to install 250 lockers nationally by the end of 2014.
"The locations we choose to place our parcel lockers must be well-lit, accessible and secure," an Australia Post spokeswoman said.
"You can only open the parcel locker containing your parcel when you enter your one-off access codes provided to you for each parcel delivery."
The spokeswoman said the lockers formed part of Australia Post's $2 billion investment in transforming its network for a better fit with the way people want to receive parcels and access services. About 70 per cent of all parcels delivered come directly from online purchases.
Another spokeswoman said that despite media reports postal delivery frequency would not be reduced after the recent announcement of of 900 headquarters and administration redundancies.
From this Christmas Australia Post would deliver parcels on Saturdays and extend guaranteed next-day Express Post to households six days a week, she said.
