Migrant and Refugee Settlement Services is seeking continued funding and financial support of $150,000 each year from the ACT government, to tackle the increasing numbers of clients.

In its submission to the ACT government budget consultation, the organisation stated that its client numbers had surged from less than 100 in 2008 to more than 450 as of June 30 last year.

"This is a fourfold increase and has quadrupled the call on MARSS resources," it read.

"Services have needed to be adjusted to cope with this demand."

The ACT government has funded the organisation since the federal government withdrew its support in 2008, the submission stated.

The then chief minister Jon Stanhope agreed to a limited support package of about $50,000 a year, an agreement which concludes this year and leaves the future funding of the services in doubt.

The organisation stated only eligible-visa people who had arrived in Australia within the last five years were funded by the federal government, meaning people such as asylum seekers were "not funded at all".

It also described Canberra and its citizens as an example of how compassionate people can be, often welcoming refugees whose settlement fails in Sydney or Melbourne.

"MARSS has received no financial assistance to help these secondary migrants as the funds given by the federal government for assistance to migrants is generally linked to the primary migrant status," it read.

"There is an increasing demand on the services of MARSS due to the influx of refugees and other humanitarian entrants into Canberra. This trend is not expected to reduce.''
