CD-ROM Programs
You may elect to purchase the CD-ROM programs online by credit or debit card or offline by direct deposit, money order or cheque in Australian dollars. We cannot accept any other form of offline payment. The product will be sent by registered Australian Post. We shall be under no obligation to send the product until payment has been made in full, unless you have chosen to pay by instalments, in which case the product will be dispatched after the first instalment has been paid.

Membership Plan Fees
The fees payable for Membership (“Membership Fee”) as well as any applicable GST are as set out on our website from time to time. We reserve the right to vary the Membership Fee upon renewal of your Membership by notice in writing.

The Membership Fee is payable in advance. You may elect to pay the Membership Fee online by credit or debit card or offline by direct deposit, money order or cheque in Australian dollars. We cannot accept any other form of offline payment. We shall be under no obligation to provide the Service until the Membership Fee has been paid in full.

For Monthly Memberships: Unless you give notice of your intention to terminate your membership prior to the end of your current membership term, your membership will be automatically renewed for an additional equivalent term at the Subscription Fee notified to you. If you have elected to pay online, payment will be automatically debited from your account by our payment provider upon renewal. If your account details have changed, or if you have elected to pay offline and fail to pay the Subscription Fee before your current membership expires then we may suspend your access to the Service until your Subscription Fee is paid.

For Six-Monthly and Annual Memberships: We will send you a courtesy reminder by email advising when your membership is due to expire. You will be given the option to renew your membership upon payment of a further Subscription Fee. Your membership will NOT be automatically renewed upon expiry of the membership.

Mathematics.com.au will notify you by email at least one month in advance of any change in the Membership fee for your membership plan. You will have the option of accepting the change, moving to another membership plan or canceling the service. If we do not receive a response from you, we will charge your credit card at the new fee from your next billing date until we receive alternative instructions from you.

If your credit card details change, you must contact member services with your new card details; otherwise we will put your membership on hold and suspend your access to the Service.

Tax invoices for the payment of your Membership fees can be created and sent to you on request.
