A small sinkhole opened up on Newcastle's main street in front of a busy convenience store.
The hole, located on Hunter Street opposite the Newcastle Herald office, appeared on Tuesday and is about half-a-metre deep.
Newcastle City Council has been notified of the depression, which appears to be dry underneath the ruptured concrete.
The region's long mining history means it's no stranger to sinkholes.
In March last year, 40 residents were evacuated from a Wallsend neighbourhood due to a mine subsidence, which affected about 100-square-metres, including about $3-million of damage to the Wallsend Bowling Club.
In 2019, a sinkhole appeared in the CBD, near the kerb on the corner of King and Bolton streets.
A decade ago, two separate sinkholes opened up in a residential street in Swansea, barely sparing one family's home.
The first was 20 metres wide and 10m deep and collapsed above an old 20-metre, vertical-furnace shaft in a couple's front yard while they were out.
It sent tonnes of dirt and bricks into a workshop below, almost taking the front bedroom with it. A second, two-metre hole appeared two doors down less than 12 hours later.
