Katherine wildlife rangers have trapped their biggest crocodile of the year so far.
The capture of a 4.4-metre saltwater crocodile was the second in about a week after a "quieter" than usual dry season.
This latest capture was trapped in the Flora River Nature Park, south west of Katherine, in the Northern Territory on Friday.
The same rangers caught a 3.3 metre saltie four days earlier also downstream of Katherine but this time at Taylors Park.
Crocodiles are on the move because of the rising temperatures, Senior NT Parks wildlife ranger John Burke said.
WHAT ELSE IS HAPPENING:
The capture comes despite the low flow of the river and the few crocs caught after two poor wet seasons in the Katherine region.
Mr Burke said the capture of the crocodiles was a "serious reminder you are in croc country".
"Crocodiles can be found in any waterway in the Top End region and you should always be crocwise."
Many people have remarked in the large numbers of people seen swimming in the Low Level Reserve because of the unseasonal heat and the dangers of crocodiles.
Because of border closures and the low numbers of nomads in the area, most of these people are believed to be Territorians taking advantage of $200 tourist vouchers.
"Never be complacent around the water and only swim in designated swimming areas or pools," Mr Burke said.
A male saltwater croc measuring 4.71 metres long - as long as the average family car - was trapped by Katherine rangers in July 2018 at Taylor's Park boat ramp.
That monster was believed to be the biggest taken from the Katherine River in many years.
Five metre salties are considered a rarity in NT's inland waters.
A 6.4m saltwater crocodile was caught in a net on the Mary River in 1974. The animal was killed and its head removed by an axe.
A total of 167 saltwater crocodiles have been captured in the Top End this year.
