Explain Bougainville, NCD’s positions

CAN someone from the Department of Provincial and Local Level Government clarify whether District Development Authority (DDA) Act 2014 apply to Bougainville and National Capital District (NCD).
Section 2 of the Act explicitly states that the Act does not apply to Bougainville or NCD but Bougainville and NCD MPs have established DDA boards to approve funding in their electorates.
In my view as a layman, this is illegal.
Bougainville and NCD governments cannot establish development authority boards if the Act does not apply to them.
MPs from these electorates may be illegally spending money.
Funding should be channelled through budgetary process in the Autonomous Bougainville Government and NCD Commission because they have separate laws governing their operations when it comes to dealing with Government funding.
Over to the Department of Provincial and Local Level Government for clarification.
