Ann: Quarterly Activities Report, page-59

Math so far

	Column 1
0	$3.2 Billion New federal funding
1	$2.2 WA supplied funding
2	$5.4 billion Total

	Column 1	Column 2	Column 3
0	1.67	billion	Major Roads Projects
1	1.05	billion	Metro net
2	0.5	billion	50% Ellenbrook train line (cost 1 billion WA Govt. to supply other half)
3	0.5	billion	50% share by WA Govt. of above
4	0.189	billion	3 x hospital Upgrades
5	0.14	billion	Water Project
6
7	4.049	billion

I'm assuming unaccounted for dollars lie in the WA Govt. Budget discretion.
Not included is $489 million GST top up to be used on the Forrestfield rail line
