This autumn has been the fourth-warmest on record in Australia, with below average rainfall for most of the country, according to the Bureau of Meteorology's autumn summary.

So how bad is the drought and why has it been so dry?

According to Blair Trewin, a senior climatologist at the bureau, the areas experiencing the most significant drought at the moment are in New South Wales, north-west Victoria and eastern South Australia.

"Many parts of central and eastern New South Wales have had well below average rainfall, really since April last year," Dr Trewin said.

The last time an autumn was this dry in southern Australia, women were just getting the right to vote in federal elections and the Boer War was ending.

"Since the start of this year, the dry conditions have spread to cover most inland parts of the state."

Rain over the past few weeks in Western Australia has eased drought conditions there although some areas, particularly east of Albany in the state's south, remain dry.

Dr Trewin said the current conditions were the driest on record over a 14-month period for areas of NSW, including the upper Hunter, parts of the Illawarra and Southern Highlands, and an area in the central-west.

The savings have proven a big bright side to a tough year. So how bad is the drought ? The biggest impact of warmer temperatures has been that they intensify the effects of drought , increasing evaporation and drying out the soil.

The last time an autumn was this dry in southern Australia, women were just getting the right to vote in federal elections and the Boer War was ending.

"When you look at the time scale of six months through to a year, it's a significant [drought] in the worst-affected parts of NSW," he said.

The only autumn on record drier than this one in southern Australia was in 1902, the year the Federation drought peaked, the Boer War ended, and women got the right to vote in New South Wales and federal elections.

During the Federation drought, the Darling River virtually ran dry at Bourke in NSW, and the Australian wheat crop was all but lost.

The current dry is not as extensive as the long-term droughts of the past.

"We certainly don't have those long-term drought conditions in New South Wales in the way that we had in the 1900s or the 1940s or 2000s," Dr Trewin said.

"1902 was a very bad year in its own right, but it actually came at the end of a prolonged period of dry weather which spanned seven to eight years.

"We've had nothing like that recently because 2016 was a really wet year for just about all of the regions."

Trad unapologetic about 'borrowing to build' in budget

  Trad unapologetic about 'borrowing to build' in budget The Queensland government has no plan for paying down the state's debt – predicted to reach $83 billion in four years – and no intention of doing so. Treasurer Jackie Trad today delivered her first budget – this government’s fourth – spruiking a surplus of $1.512 billion in 2017-18, but refusing to apologise for the state’s borrowing bill.Coal and gas pumped $4 billion into the economy in 2017-18, an increase of $1 billion on the amount predicted in the last budget.At 10 percent of its economy, the state’s debt is “stable” and “responsible” because the economy is growing, she said.

How bad is it ? According to government data, the average annual per capita water availability fell 15% between 2001-2011. A common cause of this is drought and lack of access to irrigation facilities. A 2017 study found that nearly 60,000 farmers had committed suicide in the past three decades due to

However, Dr Trewin said parts of inland Queensland were experiencing long-term rainfall deficits.

Why is it so dry?

Dr Trewin said the dry conditions were due to what hadn't been happening, rather than what had. The systems which usually bring rain simply haven't come for New South Wales.

"During the summer, you're often looking at a feed of tropical moisture, when you get moisture feeding in from the tropical monsoon coming south," he said.

"But that didn't really happen this year, all the rain stayed in the tropics this time round."

There also haven't been any major feeds of Indian Ocean moisture from the north-west approaching fronts or east coast lows in the affected regions.

"There was an event in March which produced a lot of rain on the coast from about Newcastle northwards. But it had basically no effect inland and no effect south of Newcastle," Dr Trewin said.

Why aren't the systems coming?

Dr Trewin said the east coast lows tended to be random.

"But the lack of a major north-west feed [of moisture] is connected to sea surface temperatures in the Indian Ocean not being as warm as they were in 2016, for example."

He said another common theme in recent winters was a stronger than usual sub-tropical ridge over southern Australia.

"That means that frontal systems that would normally start affecting southern Australia more generally during the winter are instead mostly passing south of the continent, really only affecting Tasmania and perhaps southern Victoria."

This is not a one-off

University of Melbourne PhD candidate Mandy Freud is studying past Australian climates, using corals, ice cores, tree rings and cave records to investigate what the climate was like up to 800 years ago.

Ms Freud said she had been looking at 30 and 50 year trends in warm and cool season rainfall, going back 400 years.

"It looks like the north is getting wetter during the warm season when they get all the rain and the south is getting drier during the cold season when actually a lot of rain falls in the south," she said.

"If we look at the cool season, we can see that the Murray Darling Basin has quite an unusual declining trend in rainfall for the past 30 years."

Ms Freud said central to northern NSW did not have any discernible trends, and south-west WA was variable, with recent declines in cool season rainfall.

"We can say that there has been a decline in rainfall over almost the past 50 years. There's a decline of about three millimetres a year that we can see in south-west WA."

"We think it has something to do with a change in the Southern Annular Mode."

The Southern Annular Mode (SAM) describes how far the westerly wind belt can move up into the south of Australia.

It's these westerlies that traditionally bring rain to southern Australia in autumn and winter. High pressure over Australia can block these lows from getting though, causing a positive SAM and low cool season rainfall for southern Australia.

The outlook for winter

The Bureau of Meteorology is forecasting that winter is likely to be drier than average in south-east Australia and parts of WA, particularly in June.

"It we were to have significantly below normal rainfall through the winter, which is what the outlook is pointing towards, that would clearly exacerbate the rainfall deficits that we currently have," Dr Trewin said.

Robbie Farah could make a shock return to Wests Tigers, giving the veteran hooker a chance for a more fitting farewell at the club where his career began.Fairfax Media can reveal Farah has reached out to Tigers coach Ivan Cleary about the prospect of coming back to the joint-venture outfit before the June 30 transfer deadline. The deal would only be until the end of the season and it's likely his current side, South Sydney, won’t stand in the way.
