A top official at the Solomon Islands finance ministry says it is doing all it can to stop fraud.
The comment follows the discovery of almost two million US dollars worth of financial irregularity related to a programme for the building of hospitals and clinics involving both AusAid and government money.
The finance permanent secretary says three finance ministry staff and five from the health ministry have been suspended while the matter is investigated.
Shadrach Fanega says recent auditing improvements facilitated the fraud's discovery.
"We're working towards ensuring governance is improved, the financial instructions are improved, the manuals for procurement are improved, and of course with the recent passage of the Public Financial Management Act, that should be able to enhance our efforts to be able to curb these kind of practices."
Shadrach Fanega says investigations into the transactions of other ministries will follow.
