Federated Farmers is exploring ways the advocacy group can support Australian farmers impacted by the horrific drought conditions they face.
Much of southeastern Australia is struggling with drought but conditions in New South Wales are the driest and most widespread since 1965.
The new rules will increase culling quotas and more shooters to operate under a single license, a government press release states.
The drought may be Australia's worst in 400 years, according to a recent University of Melbourne study, which reconstructed 800 years of seasonal patterns.
Farmers have also had to ration water for their families and their herds because the dams on their properties are dry or almost empty.
A drier-than-expected June and July has left many farmers with failing crops, a short supply of water and diminishing livestock feed.
"If we don't manage this situation, we will start to see tens of thousands of kangaroos starving and suffering, ultimately leading to a major animal welfare crisis", he added.

Alongside direct employment, the investment is expected to help create 700,000 new jobs in related industries and businesses. Samsung said it will also bolster its mainstay chip business, which is already the major source of profit for the company.
The government also relaxed restrictions on shooting kangaroos in a bid to help farmers as the animals compete with livestock for grazing land.
The requirement to tag dead kangaroos to keep a tally of the number shot across the state had been dispensed with.
"Australia's rainfall varies greatly from one year to the next and from one decade to the next, and is strongly influenced by large scale phenomena such as El Niño and La Niña", Australia's Department of the Environment and Energy says on its website.
The Bureau of Meteorology's latest climate outlook for the next three months is predicting high chances of warmer and drier conditions over the drought-affected regions.
Though Australia has long suffered from spells of drought, other parts of the world are now experiencing extreme weather which experts say is evidence of the Earth's changing climate.
However, the state government has refused to officially declare the drought a natural disaster akin to a flood or bushfire and ignored an offer of military help.
