Customer service centres will be open by appointment only.

"While in most instances, this means staff and customers will not have face to face contact, Local Land Services is still here to help in these challenging times," South East Local Land Services' general manager, Anthony Marshall said.

"We are setting up new systems to ensure customer enquiries are attended to by the right people in a timely manner," Mr Marshall said.

Customers can keep in touch with Local Land Services in a variety of ways including by filling out an online enquiry form, via Facebook messenger or by calling 1300 799 795.

Online enquires will be responded to within two working days by return email or a phone call and online payments are still available on the Local Land Services website.

People can call a single customer number from anywhere in the state and be put through to regional staff while those on Facebook can also get in touch via messenger.

"In addition, we may be sending out important information via email so we advise people to stay in touch by subscribing to the South East Circular," Marshall said.

Local Land Services will continue to provide essential on-ground services, such as biosecurity and emergency management where safe and practical.

"During this current period, the way we interact with our customers and the community may be different to what people are used to, but we are still here when it matters".
