Income investors are spoilt for choice on the Australian share market.

There are countless ASX dividend shares to choose from offering attractive yields. But which ones could be buys?

Let's look at three that brokers rate highly right now. They are as follows:

Dicker Data Ltd (ASX: DDR)

Dicker Data could be an ASX dividend share to buy. It is a technology distributor that supplies software, hardware, cloud, and cybersecurity solutions across Australia.

It has been growing its earnings and dividends at a solid rate for well over a decade. And as the tech sector continues to expand, Dicker Data appears well-placed to continue this trend.

The team at UBS is positive on the company and reaffirmed its buy rating last month with a $9.30 price target.

As for income, the broker is forecasting fully franked dividends of 45 cents per share in FY 2025 and then 51 cents in FY 2026. Based on its current share price of $8.11, this equates to dividend yields of 5.5% in 2025 and 6.3%, respectively.

GQG Partners Inc. (ASX: GQG)

Another ASX dividend share that could be a top buy is GQG Partners.

It is a global boutique asset management company focused on active equity portfolios.

Macquarie is bullish on the company and has an outperform rating and $2.90 price target on its shares. It notes that "at <9x NTM P/E with a >10% yield, valuation remains attractive."

Speaking of yields, the broker is forecasting dividends of 14.7 US cents (22.7 Australian cents) per share in FY 2025 and 16 US cents (24.8 Australian cents) per share in FY 2026. Based on its current share price of $2.12, this equates to massive dividend yields of 10.7% and 11.7%, respectively.

Telstra Group Ltd (ASX: TLS)

Finally, Telstra could be an ASX dividend share to buy now according to brokers.

With strong cash flow from its mobile and infrastructure businesses, a streamlined cost base, improving profitability, and a new Connected Future 30 strategy, the telco giant appears well placed to continue growing its dividends over time.

Macquarie is also a big fan of Telstra. It has an outperform rating and $5.28 price target on its shares. In response to its new strategy, the broker said: "Despite execution risks from software-defined networking, ROIC growth and focus on the core competitive advantage in network and connectivity signals operating leverage and momentum."

As for income, the broker is forecasting fully franked dividends per share of 19.9 cents in FY 2025 and then 22 cents in FY 2026. Based on its current share price of $4.87, this equates to dividend yields of 4.1% and 4.5%, respectively.
