Ga. Code § 8-3-307
Members of the commission shall serve without compensation but shall receive the same expense allowance per day as that received by a member of the General Assembly for each day such member is in physical attendance at a commission meeting, plus either reimbursement for actual transportation costs while traveling by public carrier or the same mileage allowance for use of a personal car in connection with such attendance as members of the General Assembly receive. Notwithstanding the foregoing, no member shall receive said expense allowance or travel reimbursement if said member is entitled to receive an expense allowance or travel reimbursement or salary for performance of duties on some other state board, commission, or entity, by whatever name called, for work performed on that day in the same location. Expense allowances and travel reimbursement shall be paid from moneys appropriated or otherwise available to the trust fund.
