The
1965-68 drought
The
decade from 1957 was generally dry, and could be compared with the droughts
of 1895-1903 and 1937-45 in area and severity. Large areas of central
Australia, and to a lesser extent, northern Australia, were affected
to varying degrees between 1957 and 1964. The odd years in this period
tended to be worse, with some relief in the intervening even years.
Eastern Australia suffered less up to 1964, but was greatly affected
from 1965 to 1968; this latter phase of the drought is described here.
Towards
the end of 1964 drought developed over northwestern New South Wales,
and then to most of the country in 1965, sparing only Western Australia
and the far north. The first six months of 1965 were especially dry
over the eastern states, central Australia and South Australia. Canberra
received just 26mm (9 percent of average) between January and May. In
South Australia, better rains from July to September 1965 enabled a
satisfactory wheat crop, though this was spoilt somewhat by hot, dry
conditions in October. NSW and Queensland received temporary relief
in December, before another hot, dry interlude over NSW ended with good
rain in March 1966.
The
trend for even years to be generally wetter continued, with above-average
rains in the second half of 1966 over most of Australia, save in Queensland
and Tasmania. Record August rains provided timely relief over inland
pastoral districts of Queensland, but in Tasmania a dry end to 1966
set the scene for disastrous fires early in 1967.
Intense
drought returned to southeastern Australia in 1967: the first six months
were the driest January-June period this century over large areas of
Victoria, southeastern South Australia, and northeastern Tasmania. Unseasonal
dust-storms ripped across South Australia in late May (reducing visibility
in Adelaide to just one kilometre on the 29th), and again in late July.
By now, parts of southwestern Victoria were being declared drought areas.
Though wheat was sown, yields were greatly limited due to the return
of extremely dry conditions from mid-September. The oat crop was virtually
wiped out. Large numbers of stock were moved from western Victoria to
Gippsland and parts of NSW, but even in these areas conditions were
deteriorating by November. In Melbourne, 1967 remains the driest year
in its 140 years of records.
The
drought began to break early in 1968, first with heavy rains in early
January over northern South Australia, and over the rest of that state
(except the southeast) in mid-January. By March, useful rains had fallen
in most areas, but drought lingered in southern and eastern Victoria
until copious rains in late April and May finally put an end to it.
Most of Australia had good rains in 1968, except the NSW coast south
from Newcastle: rainfall at Sydney and Eden in 1968 was the lowest for
80 years. Severe spring bushfires flared in the Blue Mountains, but
general rain in December finally ended the drought.
