Queensland Senator Pauline Hanson’s plans to lead the campaign opposing the referendum to enshrine a First Nations’ “voice” to Federal Parliament in the Constitution faces a delay after a major incident outside her One Nation Party’s national headquarters in Brisbane.

Senator Hansen and senior One Nation strategists have been unable to access their party headquarters to kickstart their “no” campaign after it was isolated as a result of traffic gridlock that formed on Tuesday when dozens and then hundreds of dogs descended on the scene. (main picture)

A Queensland Police spokesperson said officers were still on the scene trying to ease the massive traffic jam and had sought help from the RSPCA to round up the dogs and reopen roads in the suburb and beyond.

The One Nation Party shares an office building in the semi-industrial suburb of Eagle Farm near the Brisbane Airport with dog whistle manufacturer and distributor Hear Boy Pty Ltd.

Senator Hansen and a spokesperson for One Nation would not comment on the incident which has impacted surrounding roads and suburbs and the families and businesses located in the area.

General manager of the Hear Boy firm, Jack Russell, said despite the chaos affecting Eagle Farm and surrounding areas his firm’s operations had not been impacted.

“Oddly enough the massive multi-suburb traffic jam and the huge swarm of dogs haven’t affected our business at all,” Mr Russell explained.

“Luckily for us a chap from the One Nation office popped in just before the dogs turned up and bought every single one of the thousands of dog whistles we had in stock.

“In fact he bought up dog whistles representing several year’s worth of production from us.

“So we’re happy to sit tight for days, weeks or even months – possible a few years – if it takes that long to sort out the mess,” he said.
