But when that missing something is a precious three-year-old boy who vanished several years ago, returning to the scene of his disappearance must be nothing short of chilling.

Today NSW Police officers returned to the property where William Tyrrell was last seen playing before he went missing in 2014.

There are unsubstantiated theories that the police investigation is looking at whether William may have fallen from a balcony at the property.

NSW Police announced yesterday that new evidence in the seven-year investigation would result in a series of "high intensity" searches at three specific locations in Kendall on the NSW north coast.

It was also the first time in the long investigation that police have acknowledged that William is most likely deceased.

NSW Police Commissioner Mick Fuller said today on 2GB that he believes the investigation 'will be solved' and confirmed there is 'one person in particular (they) are looking at'.

And it's a case I am sure many of us would like to see solved as well.

Another mystery waiting to be solved is the origin point of the Northern Territory's recent COVID outbreak.

There are nine cases in the new cluster and it is not known yet if these cases are linked to one involving a 21-year-old woman to travelled to the Territory from Queensland.

However, a Northern Territory Senator has revealed that her sister was the source of the first COVID-19 outbreak in a remote NT community.

The recent outbreak has resulted in further lockdowns for the territory.

Further south, NSW residents in the state's central west are gearing up for floods - check out this incredible footage of the floods from the air.

The Lachlan River is expected to reach the major flood level tonight, which the Bureau of Meteorology reports is a little higher than the major flood event in 2016.

The bureau has also predicted that the impact of the flood could be similar to the 2016 flood, when more than 200 people were evacuated from their homes.

But it's not just wild weather that should have homeowners on high alert.

The Reserve Bank of Australia has flagged that booming housing prices could increase inequality - and even push low-income earners into poverty.

It's a grim assessment, but one that most of us would have seen coming.

There are a lot of dual (or more) income families out there who simply cannot afford to buy a home within reasonable cooee of their workplace due to surging prices.

"If you own your own home at the point you retire that's basically the thing you need to do to not be in poverty in retirement," RBA assistant governor Luci Ellis said.

Well... here's hoping that something can be done to fix this mess before a generation of Aussies end up in poverty, hey?
