The cat is out of the bag. Bank shares have shot up since the surprise election result as new investors pile onto the great franking credits bandwagon.

_Hey, you got any of these franking credits, o_lder bloke asks mate. Its two days post-election. Im on my regular break from my home desk with my dog, Mackie, in Kews_affogato_central. Leafy Kew was at the heart of Kooyongs electoral battleground. The two men are at an adjoining table at the cafe. Theyre talking about the franking credits campaign the pitched battle to win the retiree vote._No,_is the reply,but Im gonna look into them.

That night, Im on my way to Hamer Hall to an ACO concert with old pal, Rex._Ive transferred all my money into bank shares,_he announces, awaiting my reaction. Then to press home the point, he jabs me in the ribs_I not only get all that free money but the share price has gone up!_He laughs. And he voted Greens!

Fast forward to the end of the week and Im back in Kew cafe-land with the four-legged one, getting my coffee fix again. Its a different cafe. Were seated outside. A couple of elders go past. My ears prick up.theyre talking about franking credits. But theyre not congratulating themselves for keeping Bill Shortens hands off their free money. No, theyre wondering how they can get_their_hands on some! Jeez

Seriously, how good is Tim Wilson and cousin Kevin, or is it Geoff?

Few of us silly old duffers had a bloody clue about franking credits until Tim and cousin Geoff started jumping up and down championing the unique advantage of owning shares with franking credits. And how good is Australia the only country in the world to offer a cash reward!

Tim took care of the Parliamentary Inquiry and the town hall meetings focussing on the high retiree states of Tassie and Queensland. Geoff harnessed his travelling roadshow, Wilson Asset Management, and headed up north to spread the word. Between them, they sparked ire in the hearts of Queenslanders and Tasmanians. Not only would they lose all that free money, but the world as they knew it would end. Worked a charm.

Post-election, Geoff was itching to congratulate himself for alerting the voters about franking credits. And avoiding Armageddon. Claimed his campaignhelped deliver a fatal blowto Labors hopes of election. But hes too modest by half. Thanks to the Wilson boys, not one of the nearly four million over 65s would be now be unaware of the free moneygig when they retire. What a legacy, boys!

So, now we oldies have been enlightened, have we shown our gratitude, especially to Tim? Such a formidable force for good should surely have been promoted to cabinet! Whats wrong with ScoMo? This reporter still remembers saluting Tim forduking it out(single-handedly, mind) against the Labor Governments plain packaging proposals for ciggie packets.

Wilson the Younger stormed the airwaves on behalf of Big Tobacco, clocking up 13 radio interviews in one day, a robust opinion piece in_The Australian,and managed to pop up, fresh as a daisy, on prime time_7.30 Report_that night. Be afraid, he warned. Be very afraid. This outrageous plan would cost the public $3 billion in compensation! If our government took away a companys logo, it could be seen as_stealing! Good to see Tim working_with_the government and on our side now!

So, on 22 May, I put out a Tweet to gauge the level of gratitude to Tim. It had over 10,000 impressions in the first day. By next day, over 20,000. Then when Westy got into the act, he upped the score to 67,500 impressions, 3,700 engagements, 1750 link clicks,1000 likes and over 600 RTs in just one day.

I was personally inundated with responses (especially after an interview on ABC Radio Sydney yesterday). Was a spot worried Id be seen as a self-serving, greedy oldie, you know, one of those solipsistic slackers that journos like Bernard Keane like to target. There was the expected bit of unfriendly fire but, by and large, I could tell the Tweeps were genuinely grateful to Tim. Geoff reported that his superannuation fund adviser told him theyd been bombarded with clients asking about this gift of free money and how could they access this?

So, does anyone in Australia now NOT KNOW they can get #FreeMoney for investing in things like banks if theyve retired and want to set up their own fund? And the more of you who buy shares, the more the shares will go up! Double whammy! Win, Win! Whoohoo! As I said, how good is Tim Wilson? Get into it, guys. Follow me!

Editors Note: Treasury found up to 230,000 pensioners would have been affected by Labors original policy. The value of franking credits refunded has increased from $1.9 billion in 2005-06 to $5.9 billion in 2014-15, Treasury found. It is now projected to increase to $8 billion a year although theAFR foundthere were $16 billion in franking credits generated in the recent earnings season on the ASX.
