“I saw two four-wheel-drives cutting sick, and I saw kangaroos running around. I [watched] it for probably 30 seconds, at which point the small four-wheel drive ... it came to a sudden stop like it had hit something.

“There was just a big dust cloud of grey sand. I immediately ran inside, grabbed my phone, ducked back outside to see if it was still going on.”

Chardei said she quickly called the ranger only for her call to ring out, and she immediately began canvassing her neighbours to find if anyone had taken photos or videos of the incident.

After the four-wheel-drives had left the scene, Chardei said residents discovered up to three adult kangaroos dead in the clearing.

A neighbour also eventually located an abandoned and injured joey on her property, which she handed over to a local wildlife carer.

After failing to hear back from the Shire of Harvey ranger, Chardei contacted WA Police about the incident.

But she said she was told police were unable to help, and to try to contact her local ranger again.

Chardei also reached out to the RSPCA, and the Department of Biodiversity, Conservation and Attraction.

"This was all within the first week to week and a half of January," she said. "I heard nothing back ... so then a couple of weeks ago, I contacted Nola Marino's office in Bunbury and I told them what had gone on.

“They said because I'd contacted all the state departments, I'd need to contact the state member of parliament so I contacted their office and they marked it as urgent.

“The next day I heard back from DBCA. The woman from the department ... she said, 'in the video, you couldn't actually see them hitting a kangaroo. Did you see them hit a kangaroo?'

“And I said I can't say for certain that I did. I know they hit something and there were dead kangaroos out there, immediately after.

“But in the video footage [all] you could just see was the kangaroos running wild.”

Chardei said that was when the investigation seemed to stall. Then earlier this month, the kangaroos were targeted again.

Four men were seen throwing rocks at kangaroos near the lakes on Braidwood, and it’s understood the incident was again reported to the Shire of Harvey ranger.

And at the weekend, residents were forced to intervene when a group of children were seen throwing rocks at the animals and herding them towards a lake on the residential estate.

Resident Gale* was outside watering her plants when she watched the group of children arrive early on Saturday morning.

"They took their shirts off so they could try and blend in," she said. "They were saying to each other: 'Come on we're going after these kangaroos, let's go over here.'

"So I said, 'no guys, stop. This is their home. They're our friends, just leave them alone'."

According to Gale, the children left for a short period of time but came back to the estate around midday.

Fellow resident Reily also saw the children arrive.

"I was riding my bike with my boyfriend and dog around the estate, probably around [midday]," she said.

"We saw three little girls just chasing the kangaroos. We didn't think much of it but then the older one ... threw quite a large brick of piece of concrete at this little kangaroo.

“We yelled out 'what are you doing?' so we went up to them to talk to them and they said they were ushering the kangaroos towards their older brothers at the river.

"I'm pretty sure it didn't get hit... but [the kangaroo] really wasn’t very old. All the little kangaroos at the moment are probably knee-height so it easily could have gotten broken ribs or a jaw –[if] it was hit."

Gale said she then watched as the young boys assembled near the estate’s lake.

"They were herding the kangaroos down towards the river where these other kids were waiting with these sticks and rocks," she said. "I had heard one shouting 'we're going to go for the one with the joey!'

"There was a lot of yelling and screaming at each other and about the kangaroos about what to do."

Reily said she called the ranger, but was told they were not interested.

"He said it was nothing to do with him," she said.

Reily phoned police, who arrived about 45 minutes after the children had left.

The residents have not found any injured kangaroos from the weekend, but have called for better clarity on who to call to report future incidents.

The RSPCA said it had been notified about Chardei’s report regarding the 4WDs and had passed on the information to the Department of Biodiversity, Conservation and Attractions.

"On 4 January 2019, RSPCA WA received a cruelty report detailing a disturbing incident in which several people were attempting to run down kangaroos with their cars in Australind," a spokeswoman said.

"RSPCA WA is deeply concerned to hear about any instances of cruelty against vulnerable animals, but especially instances where the abuse is intentional and deliberate – there’s absolutely no excuse for it."

WA Police also confirmed they had been notified about the 4WD incident, but it hadn’t been referred to police to investigate.

There doesn't seem to be any consequences.

Gale, a local resident

Australind police said they had not been notified about incidents on the estate since the January 2 case, but said they would continue to assist other agencies with investigations into animal cruelty when requested.

“Members of the community who see anyone acting in a way that may harm wildlife should call Police immediately on 131 444,” a spokesman said.

The Shire of Harvey confirmed it had been called to the most recent incident at the weekend, but the person who called had been referred to other agencies.

A shire representative said the ranger had no authority to make arrests or prosecute and the weekend incident was considered a police matter.

"There doesn't seem to be any consequence for anybody who think these kangaroos are just fair game for a bit of fun and nonsense," Gale said.

Chardei agreed and said there needed to be stronger supervision of those responsible for terrorising the animals.

"You go down to the end of my street and there's a beautiful grassed area and in the morning, the kangaroos are sitting there and they're peaceful," she said.

"They are absolutely beautiful - but they're just getting attacked."
