Police on the south coast have been investigating supply of the two drugs in the Batemans Bay area as part of Strike Force Nello since May.

Officers seized cannabis, methylamphetamine and an electronic stun-gun when they searched houses in Sunshine Bay and Fishermans Paradise on Thursday.

They arrested a woman, 39, at the Sunshine Bay house and she was later charged with participating in a criminal group and four counts of supplying a prohibited drug.

She allegedly supplied at least 24 grams of ice on 241 occasions between May 7 and July 3.

A husband and wife, both aged 38, were arrested at the Fishermans Paradise home.

The man was charged with numerous offences related to drug supply and possession, possessing ammunition without a licence and taking part in a criminal group.

He allegedly supplied at least 25 grams of ice on nine separate occasions in the past two months.

The woman was also charged with drug supply and possession charges, having a weapon without a permit and taking part in a criminal group.

Police allege she supplied at least 10.5 grams of ice on three separate occasions.

The man and woman have been granted conditional bail and will face Milton Local Court later this month.

The 39-year-old woman was refused bail and will face Batemans Bay Local Court on Friday.
