A new prison at Bang Jo in central Phuket will replace the ancient jail where so many male and female inmates are packed in that the International Red Cross is believed to have lodged a formal complaint.
Once again it appears that the military commanders who now rule Thailand are quickly sorting out Phuket problems that have been left unsorted by governments on both sides of Thailand's political divide for decades.
News of the budget approval will delight the Phuket Prison Commander Rapin Nichanon, who revealed the design for a new Phuket prison two years ago.
Back in 2012 he told Phuketwan that the new prison for Phuket would be built to international standards, contain cells rather than dormitories and end concerns about human rights.
A maximum number of eight people will be in each cell.
At present, as many as 300 prisoners shares dormitories that are so crowded there isn't space for them all to sleep on their backs, or to stretch their legs out straight.
It has yet to be made plain whether prisoners on remand awaiting trial will be separated from those who have been convicted in the new facility.
At present, all prisoners mingle, whether or not they have been tried and sentenced.
More than 80 percent of those in Phuket Prison are there because of drugs.
Commander Rapin said in revealing the design of the new prison back in 2012: '''We see this as an opportunity to end the antiquated system where prisoners must wear shackles to court, and apply new technology instead.'''
The new prison was intended to cope with 3000 inmates but like Phuket International Airport, Phuket and its prison has proved more popular than anticipated by officials.
The original jail, built for 750, scored a record population of 2831 last month. It would be pointless building a new prison that became too crowded too soon.
