Many of Australia's top brokers have been busy adjusting their financial models again. This has led to the release of a number of broker notes this week.

Three ASX shares brokers have named as buys this week are listed below. Here's why they are bullish on them:

According to a note out of Bell Potter, its analysts have retained their buy rating on this location technology company's shares with an improved price target of $16.25. The broker made the move in response to a positive and unexpected market update which revealed that Life360 had a record first quarter. It notes that the company's global monthly active users and global paying circles materially exceeded both its own and the market's expectations. This has led to Bell Potter lifting its revenue and earnings forecasts through to FY 2026. Together with improving sentiment thanks to the successful tech IPO of Reddit Inc (NYSE: RDDT), the broker has lifted the valuation metrics it uses for the company. The Life360 share price is currently trading at $13.74 on Wednesday.

A note out of Goldman Sachs reveals that its analysts have retained their buy rating and $8.05 price target on this airline operator's shares. This follows the announcement of a major upgrade to its Frequent Flyer program. This includes the launch of Classic Plus rewards. This will provide customers with 20 million+ more reward seats for redemption by the end of 2024. While the broker has trimmed its earnings estimates slightly in FY 2024 to reflect the change, this is offset by increases to medium term earnings estimates. As a result, it holds firm with its valuation and continues to believe that its shares are significantly undervalued. The Qantas share price is fetching $5.95 this afternoon.

Analysts at Bell Potter have retained their buy rating and $2.60 price target on this gold miner's shares. This follows the release of an update on the McPhillamys Gold project. According to the note, the broker acknowledges that the miner has increased its cost estimates materially for the gold project. However, while this is disappointing, the higher costs are expected to be offset by the stronger gold price. As a result, the broker remains positive on the company. It also sees plenty of value in its shares at the current level. The Regis Resources share price is trading at $2.10 on Wednesday afternoon.
